techmike Posted August 25, 2009 Report Share Posted August 25, 2009 The advertised pull on the Colt/Umarex is 7.5 lbs - mine measured > 10lbs - that's a bit stiff for a .22 in my book. So, I had to try to improve it. After removing the trigger group, I took it apart - single stage trigger, 3 springs - 2 for the trigger, 1 for the hammer. I stoned and polished the sear and hammer, and just for grins substituted lighter springs on the trigger. Put it all back together and functioned checked with dummy ammo. Safety A-OK. Pull measured about 5.5 lbs. Took it out to the range and loaded 1 round - accuracy was much improved! Loaded 2 rounds..... oops........ 1 trigger pull, 2 rounds fired. Loaded 3 rounds.....yep. Full auto. Brought it home and put the OEM springs back in. TM Quote Link to comment Share on other sites More sharing options...

Solscud007 Posted September 21, 2009 Report Share Posted September 21, 2009 According to a friend of mine, you were extremely lucky. Range officer found some guy who had a slam-firing AR a few years ago at the range, turned him in and the jury put him in jail for a number of years for a malfunction.
