dt00th Posted October 2, 2010 Report Share Posted October 2, 2010 i've got a tm deagle and a JG glock and the gap looked out of place on the Tm 5-7 i saw Quote Link to post Share on other sites
frogfish Posted October 3, 2010 Report Share Posted October 3, 2010 (edited) Different pistols have different designs. My TM, as well as my Marushin has no larger a gap than is on the real one. Unless the one you saw does not look like any of the others in this thread or the FN picture thread I fail to see how it is an issue. If the gap is larger than the others you see pictured then the slide was seated incorrectly but I don't think it could function properly with the slide seated incorrectly.

dt00th Posted October 3, 2010 Report Share Posted October 3, 2010 The gun i saw and used worked fine and possibly they are all the same it just look odd to me . Quote Link to post Share on other sites
renegadecow Posted October 3, 2010 Report Share Posted October 3, 2010 On the Marui 5-7, the guide rails on the BBU are separate pieces that are pegged at the front and screwed at the back. Due to excessive recoil with green gas, this is another part that fails: the pegs sheer off. The screws are still held fast but the effect is a slight tilting motion of the guide rails. When the slide is forward and in battery, there is no noticeable difference (and will not affect accuracy). But with the slide locked at the rear and with the slide lock pushing it up, the gap is more pronounced by about 0.5mm. Quote Link to post Share on other sites
Voodoo1 Posted October 3, 2010 Report Share Posted October 3, 2010 mine and badgers have an unnatural gap at the back of the the slide, where the internal frame/BBU is wearing away from the outer plastic slide Quote Link to post Share on other sites
renegadecow Posted October 3, 2010 Report Share Posted October 3, 2010 That's strange. Maybe the screw holding the BBU to the rear sight is loose? Even if the slide is worn and the BBU allowed to go go down, the rear sight will still anchor it. Quote Link to post Share on other sites
Voodoo1 Posted October 3, 2010 Report Share Posted October 3, 2010 the screw is as tight as it goes, something else is loose... will post pics when camera is running again Quote Link to post Share on other sites
dt00th Posted October 3, 2010 Report Share Posted October 3, 2010 this tm 5-7 was new out of the box maybe a mould issue ,as i say it work perfectly Quote Link to post Share on other sites
aznriptide859 Posted October 3, 2010 Report Share Posted October 3, 2010 There was an issue in mine where the gap was very large - I found the hammer mech's screws that secure it to the lower frame were loose, so I simply retightened them. Now there isn't an issue at all. Quote Link to post Share on other sites

Faint Posted October 5, 2010 Report Share Posted October 5, 2010 How are the magazines, I read they were kind of flimsy and had pretty bad gas effecicenty. Quote Link to post Share on other sites
aznriptide859 Posted October 5, 2010 Report Share Posted October 5, 2010 Not at all. They're built pretty tough (though I do oppose a bit to the loading procedure), and on a good day can last up to 3 mags worth of shots per fill. Quote Link to post Share on other sites
Faint Posted October 5, 2010 Report Share Posted October 5, 2010 Thanks, I was pretty sure it was BS, I had a 226 and it was a champ, I think a Five seveN is heading my way soon. Quote Link to post Share on other sites
frogfish Posted October 5, 2010 Report Share Posted October 5, 2010 2nd to riptides comments, although on average I get about 2.5 mags out of a fill, with the last few rounds getting weak. Quote Link to post Share on other sites
kruck Posted October 5, 2010 Report Share Posted October 5, 2010 I don't find the gas efficiency of the five seven to be very good. The only reason you get so many shots per fill is because of the huge size of the magazines (i.e. it still uses a lot of gas per shot). I usually get 60-80 shots per fill Compared to my S7 USP, which has a smaller mag, I can get up to 150 shots off of 1 fill of propane (yes really, I repeated the test several times, 1 fill of gas left to heat to room temperature, mixed rate of fire, reloading BBs as fast as I could between magazines and not heating the magazine between BB refills, got 110-150 shots per fill). So long story short, you get a lot of shots per fill on the Five Seven, but the efficiency isn't brilliant. Quote Link to post Share on other sites
renegadecow Posted October 5, 2010 Report Share Posted October 5, 2010 That's because it recoils like a *beep* and that's gonna have to come from somewhere (gas). What we really need to do is create a standardized index of just how much gas is used per shot. Like take a shot then weigh the mag difference and then create a curve with respect to temp.

kruck Posted October 5, 2010 Report Share Posted October 5, 2010 (edited) Or (mass of magazine after filling with gas) - (mass of empty magazine)/number of shots fired from gas fill = average mass of gas used per shot. I'd give it a go, but I don't have any precise scales available. Also, the USP also kicks very hard, and has a metal slide Edited October 5, 2010 by kruck Quote Link to post Share on other sites
dt00th Posted October 5, 2010 Report Share Posted October 5, 2010 You are weighing the liquid form of your choosen propellent in the mag as gas isn't that much heavier than air . Quote Link to post Share on other sites
jotohomomoto Posted October 5, 2010 Report Share Posted October 5, 2010 I am very satisfied with how many shots I get from the mags....really impressed actually. Also, do you guys have pics of the problems with the sites you are talking about? I'm not sure I understand. I was just inspecting my 5-7 to keep an eye out for such issues. thanx.

aznriptide859 Posted October 9, 2010 Report Share Posted October 9, 2010 (edited) First major failure I've had - the front part of the Guarder slide is about to blow itself off. Pictures once I stop being so lazy to pull out my pistol XD. I'm going to try and secure it tonight with some RTV silicone sealant, but, seriously, Guarder, WTH? Can you not make something that's NOT ######? EDIT: Pictures. I decided to wash the slide completely and disassemble it for fixing with sealant. After I washed it I found it had cracked along the front as well (similar to renegadecow's): I'm sorry, but Prometheus needs to come out and make a frame for this pistol - it's a really BA gun, but the fact the external support is almost only done by Guarder is just too much fail.

frogfish Posted October 10, 2010 Report Share Posted October 10, 2010 How do the internals look, did you have a creation inner slide installed? Quote Link to post Share on other sites
aznriptide859 Posted October 10, 2010 Report Share Posted October 10, 2010 I did, and part of me thinks that the fact the metal inner isn't very well secured, that it's internal movement first made me wear down the front sight (you can see on the slide where it's already moving), then somehow slamming the front part of the slide off.

frogfish Posted October 10, 2010 Report Share Posted October 10, 2010 That was gonna be my guess, as it looks like the guarder frame is made of a stronger material than the TM inner slide, so in a stock replica I would feel like the inner slide would give out first. Quote Link to post Share on other sites
renegadecow Posted October 10, 2010 Report Share Posted October 10, 2010 I dunno, the stock inner slide in mine is still perfect despite having split both the stock slide and Guarder one. But I haven't been having any more problems since the staple. My only reasoning would be since the stock inner slide is plastic, it can absorb some of the shock from the recoil. And when you have the metal inner slide on, most of the shock is transferred to the slide with the metal being inelastic. Quote Link to post Share on other sites
aznriptide859 Posted October 10, 2010 Report Share Posted October 10, 2010 I went ahead and swapped back to my TM slide w/ the plastic inner...omg the blowback feels wimpy now LOL. But renegade you make a point - I can see why that would cause the front of the slide to blow off. I don't care that the RS 5-7 doesn't have it, but I want a metal slide for this thing.
