Grease Gunner Posted October 1, 2018 Report Share Posted October 1, 2018 Hello All: A number of years ago, someone tried to disasemble a semi auto pistol and had no cluehow to do it and tried to force the parts out of the lower without separating the lower fromthe upper and got things stuck. It was sent to a repair facility and it got repaired but with an access hole drilledinto the trigger guard. Does that make any sense?I am not the one who sent it in, just the current owner Link to comment Share on other sites More sharing options...
halftrack Posted October 1, 2018 Report Share Posted October 1, 2018 (edited) Yes, it makes sense. I once had a firing pin break in half resulting in not being able to separate the frame from receiver. Out of desperation I tried to start removing parts one by one which made the situation worse. The thought was if I could remove the trigger I then would be able to fish all the internals through that hole therefore making more room for the broken firing pin to fall and finally separate the frame from the receiver. It didnt work because the trigger guard prevented the trigger from dropping completely out. The hole in your trigger guard I assume allows for the trigger to drop out through the bottom. Not a bad idea considering I had to cut my frame off and had to order a new one. Edited October 1, 2018 by halftrack Link to comment Share on other sites More sharing options...

deerslayer Posted October 11, 2018 Report Share Posted October 11, 2018 I have fixed many broken firing pin semis. The firing pin breaks in the middle and the back half dives into the trigger Assembly area. You have to know what you are doing but you can usually do laproscopic surgery and get it apart. Taking out the pivot plate is a very bad idea... Link to comment Share on other sites More sharing options...
Mainecoon Posted October 19, 2018 Report Share Posted October 19, 2018 Is there a stronger aftermarket firing pin that can be installed in these in attempt to avoid the hassle and mess of repairing the broken stock firing pin? Link to comment Share on other sites More sharing options...
Merry Ploughboy Posted October 19, 2018 Report Share Posted October 19, 2018 Is there a stronger aftermarket firing pin that can be installed in these in attempt to avoid the hassle and mess of repairing the broken stock firing pin? I'm guessing probably not. The firing pin is flat but has small, medium, and large areas which means that it is difficult to uniformly heat treat to get the desired strength and durability. In the AR-15 world, .22 and pistol caliber firing pins have a similar breakage issue due to approximately the same cause, except the firing pin is round with multiple diameters. Unlike the semi auto Thompson, the AR-15 firing pin is easy to replace; and most .22 and pistol caliber AR-15 owners carry a spare. And a question about the repair: Wouldn't it have been better to cut the leg off the trigger so that the trigger body could drop down and getting a replacement trigger instead of drilling a big hole in the trigger frame? MHO, YMMV, etc. Link to comment Share on other sites More sharing options...
StooperZero Posted October 19, 2018 Report Share Posted October 19, 2018 having the BHO pawl spring break is a treat too. but it can be taken apart when things are bouncing around inside. Link to comment Share on other sites More sharing options...
deerslayer Posted October 19, 2018 Report Share Posted October 19, 2018 There are no aftermarket better firing pins.. and the old style West Hurley pins aren't even made by anyone... So the solution becomes but a new bolt. Link to comment Share on other sites More sharing options...
T Hound Posted December 18, 2018 Report Share Posted December 18, 2018 (edited) Hmmm...interesting discussion. Haven't been unfortunate in this way yet, but food for thought. Perhaps there might bea way to modify bolts, with pins for instance, that prevent the broken halves of the firing pin from falling into the trigger partscavity and causing such a jam up. Food for thought! Edited December 18, 2018 by T Hound Link to comment Share on other sites More sharing options...
Paladin601 Posted December 18, 2018 Report Share Posted December 18, 2018 any pictures of broken firing pins? Link to comment Share on other sites More sharing options...
T Hound Posted December 20, 2018 Report Share Posted December 20, 2018 any pictures of broken firing pins?They would certainly be useful and instructive if they show a pattern of breakage. Link to comment Share on other sites More sharing options...
