Corkie121 Posted July 31, 2009 Report Share Posted July 31, 2009 Does anyone know how to go about modifying a semi-auto pistol to fire fully auto? I guess it would be to do with the sears but when I looked at my Hi-Capa it seems pretty randomly set up, any ideas would be good. Cheers for any help, Corkie Link to post Share on other sites
ertgunner Posted July 31, 2009 Report Share Posted July 31, 2009 i have been looking also airsoftcanada.com has someone doing the mod it appears to be easy http://www.youtube.com/watch?v=QVYFmbERm6Y Link to post Share on other sites
renegadecow Posted August 1, 2009 Report Share Posted August 1, 2009 FYI that mod for the Hi-Capa demands the short stroke mod to function. Without it, the hammer will be jammed underneath the slide as it goes full cycle. Link to post Share on other sites
ertgunner Posted August 1, 2009 Report Share Posted August 1, 2009 yea that's what the white piece on the recoil guide rod is for Link to post Share on other sites

Without it, the hammer will be jammed underneath the slide as it goes full cycle. I've experienced this firsthand. In order to make a HiCapa full auto, all you'd have to do is cut the disconnector sear down a tad. Take off the slide and look at the silver metal tooth to the right of the hammer if the gun's pointing away from you. Chop that metal tooth down to enable full auto. Link to post Share on other sites
ED-SKaR Posted August 1, 2009 Report Share Posted August 1, 2009 This is a bad way of causing a 1911 style gun to go fully automatic. The true way is to make the trigger linkage bar* trip the sear when the slide closes. To do this you need to shorten the triggers overtravel, so the trigger leaf is in the right place when held down. You also need to reshape the sear so that it slopes where the trigger linkage bar touches it. It helps to have a very light sear pull. *I cant remember the proper name, it touches the trigger leaf and the sear. Link to post Share on other sites

You'll also have to take the trigger group apart to get to the hammer and file off a peg on its left side. Essentially you're disabling the disconnector. Link to post Share on other sites

Does this work with other styles of pistol such as the M9 etc? Cheers so far Link to post Share on other sites

gzus11 Posted August 3, 2009 Report Share Posted August 3, 2009 its even simpler to do with the desert eagle. a similar mod can be done to the semi glocks. it may be easier to get an auto pistol Link to post Share on other sites
Wege Posted August 3, 2009 Report Share Posted August 3, 2009 real easy to do on the KSC Glocks.. but why bother when there are three models that do that already... and still keep semi..? Link to post Share on other sites
jmitc002 Posted August 30, 2009 Report Share Posted August 30, 2009 real easy to do on the KSC Glocks.. but why bother when there are three models that do that already... and still keep semi..? I presume it would be equally easy on the usp models? Any chance of getting relevant links? Link to post Share on other sites
Donut Posted August 30, 2009 Report Share Posted August 30, 2009 So... why can't you just file down the trigger sear? Link to post Share on other sites
Sale Posted September 1, 2009 Report Share Posted September 1, 2009 Disabling the disconnector is the easiest way, but this causes the hammer to follow the slide down as it closes. With most models this means the valve will be opened prematurely: the operation will be erratic compared to a dedicated select-fire model with a separate full-auto sear, which holds the hammer back until the slide goes all the way into battery. In a TM Hi-Capa and 1911 the disconnector is actuated by two independent mechanisms: the cam pin on the right side of the hammer as well as the bottom of the blowback unit. When you file down (or in the case of upgrade hammers, pull out) the pin on the right side of the hammer, you can decock the hammer manually when the magazine is removed, but the disconnector will still work because it's actuated by the blowback unit as the slide moves. If you file down the top of the disconnector as well, then the hammer will follow the slide and you have to short-stroke the slide. -Sale Link to post Share on other sites
