HamletV Posted April 9, 2020 Report Share Posted April 9, 2020 Hi guys!, I have this idea arround my head for a week!, my g17 slide has a weird wear on the top of the slide like i show in the first photo on that green line, the outer barrel sinks correctly as always But it's hitting in the top part, now has a mark that it looks like it was cracking a little bit. I don't know if this is something normal or not. I have made another thread about this But I only have one reply!(that I appreciate it!). I don't have any other problem with the gun but that thing is bothering me so much that I have that gun a side without use for now trying to figure it out what's wrong and fearing that the slide will crack or broke apart in the near future Link to post Share on other sites
Wingman Posted April 10, 2020 Report Share Posted April 10, 2020 Does the crack appear on the inside of the slide as well? Original batch of PPQ's had this issue if you used the replacement steel barrel. I believe they made modifications to the slide and the barrel. Link to post Share on other sites

No, inside the slide looks ok, nothing that looks broken, but the outer barrel of the PPQ it's compatible with a glock17? Link to post Share on other sites
renegadecow Posted April 10, 2020 Report Share Posted April 10, 2020 I think he just mentioned the PPQ as it is the most notorious for having this sort of damage. But in principle, all tilting barrel pistols with a square edge at the chamber as the locking surface are susceptible to the sort of wear. Link to post Share on other sites
Wingman Posted April 10, 2020 Report Share Posted April 10, 2020 Thank you. I should have gone into better detail of the the comparison with the PPQ. Link to post Share on other sites

So this is a normal thing?, there is no risk that the barrel ends up breaking or something? Would you be so kind and share some photos of your glock so I can see the wearing on the top of the slide?

renegadecow Posted April 10, 2020 Report Share Posted April 10, 2020 Definitely not a normal thing, just possible because of the design. Barrels can break too, usually seen on WE Glocks and Sigs but has become less common presumably due to WE improving their alloys. Only have a G42 myself and don't shoot it a lot so there's not much wear to show. Link to post Share on other sites
HamletV Posted April 11, 2020 Author Report Share Posted April 11, 2020 Umm... What should I do....., I don't wanna buy a new slide, that slide only has like 5 months!. I like glocks but  they only giveme headaches Link to post Share on other sites
Got Wood? Posted April 11, 2020 Report Share Posted April 11, 2020 Can’t you take a picture further away? It’s a bit hard to tell where the damage is and how substantial it is so close. What brand/model of Glock is it?It shouldn’t really be under any stress as such, only a rubbing motion as it the slide pushes the barrel back and down. The two shouldn’t really be colliding. Wear on the inside top edge of the slide is normal, but it looks like you’ve got a crack on the outside edge of the ejection port? Although if it’s not on the inside as well, could it just be a crack in what’s possibly paint/surface finish? Link to post Share on other sites
HamletV Posted April 11, 2020 Author Report Share Posted April 11, 2020 The glock is new, it's a king arms, the slide weights about 85 grams, probably made of aluminum Link to post Share on other sites
HamletV Posted April 11, 2020 Author Report Share Posted April 11, 2020 Here is the inside of the slide, yo can see clearly the wear Btw, the outer barrel it is worn because I filed it Link to post Share on other sites
Got Wood? Posted April 11, 2020 Report Share Posted April 11, 2020 That all looks perfectly normal. Where is the crack? Link to post Share on other sites
renegadecow Posted April 11, 2020 Report Share Posted April 11, 2020 It's on the corners of the chamber window. It is a high stress part for a brief moment, simulating the lockup function of Browning's tilting barrel. In the worst cases (PPQ) the top part of the slide breaks like a banana peel. To stop damage from happening without changing out any of the parts, you can modify the outer barrel so it has a sloped edge where it locks up with the slide or you can turn it into a non-tilting barrel completely.

Uff...... You caugh me with that! On which part should I modify?, on the green one?, the yellow?, or the blue? Link to post Share on other sites
renegadecow Posted April 12, 2020 Report Share Posted April 12, 2020 To turn it into a non-tilting type? You essentially chop off everything under then pin the outer barrel to the inner barrel in the tilted down position using a grub screw. Link to post Share on other sites
HamletV Posted April 12, 2020 Author Report Share Posted April 12, 2020 That's sounds like a lot of work!. I think I will study more the design of the whole that to see if I can get some ideas Link to post Share on other sites
Got Wood? Posted April 12, 2020 Report Share Posted April 12, 2020 Have you done this RC? I’d love to see a guide you recommend. I have w couple of spare barrels Link to post Share on other sites
HamletV Posted April 13, 2020 Author Report Share Posted April 13, 2020 Do you mean the floral engraving , unfortunately I don't have that skills, I put that photo only for reference x0, Link to post Share on other sites
Got Wood? Posted April 13, 2020 Report Share Posted April 13, 2020 Sorry I was referring to Renegadecows mention of a fixed barrel Link to post Share on other sites
renegadecow Posted April 13, 2020 Report Share Posted April 13, 2020 Did it a long time ago, no pics, but now you can buy after market non-tilting barrels for 1911s and Glocks for convenience. Link to post Share on other sites
Wingman Posted April 13, 2020 Report Share Posted April 13, 2020 I would like to see that as well. Is it necessary to increase the mainspring power? I'd like to try a "direct blowback" action on a pistol using a suppressor or tracer unit (for looks). Link to post Share on other sites
renegadecow Posted April 13, 2020 Report Share Posted April 13, 2020 The recoil spring? I don't see how it can make a difference. If anything, removing the simulated lockup function makes the slide travel smoother. Link to post Share on other sites
Wingman Posted April 13, 2020 Report Share Posted April 13, 2020 I was worried that the slide might retract during holstering as the barrel and slide is no longer locked up. Link to post Share on other sites
HamletV Posted April 14, 2020 Author Report Share Posted April 14, 2020 I think I found what is the problem!, the outer barrel was passing forward the slide stop, for the mean time, I glued to the front parte of the hop chamber a plastic sheat to block the outer barrel moving forward Link to post Share on other sites
