rowdyb Posted March 18, 2014 Share Posted March 18, 2014 I want to modify my 75b, it's currently single action only, to lift the firing pin block much sooner than it currently is being done. I know removing it is an answer, but for competition rules I can not do this. So what can be done to get the fpb engaged as soon as possible? I hate having sooo much trigger travel on a SAO gun just to reliably move the fpb. Thanks. Link to comment Share on other sites More sharing options...
Czhase Posted March 18, 2014 Share Posted March 18, 2014 (edited) You want to make it lift later, if you make it sooner the reset gets longer as does the pre travel. Edited March 18, 2014 by Czhase Link to comment Share on other sites More sharing options...
kneelingatlas Posted March 18, 2014 Share Posted March 18, 2014 Rowdy, I touched on the lifter mods at the end of my CZ tuning thread. You can take material off the 'foot' for the lifter, the area on the trigger bar which picks up the lifter and the firing pin so it clears the block sooner. I may be able to help Link to comment Share on other sites More sharing options...
alma Posted March 18, 2014 Share Posted March 18, 2014 Have you tried the CGW parts? Link to comment Share on other sites More sharing options...
kfd147 Posted March 18, 2014 Share Posted March 18, 2014 Trim the firing pin lifter leg, block, spring (cut it to about 3/4 length or get a CGW spring) and firing pin to clear sooner. Go slow it does not take much to mess up the lifter. Jason Link to comment Share on other sites More sharing options...
rowdyb Posted March 18, 2014 Author Share Posted March 18, 2014 czhase, Thank you for clarifying to me the later/sooner. This mechanism is still new-ish to me. Kneeling, I thought you were super busy? I have a pm going your way. kfd, thank you for that description. do you happen to have pics or just a little more detail?

rowdyb Posted March 18, 2014 Author Share Posted March 18, 2014 IDPA, ESP. I can run a single action gun. If I had a shadow slide I could run that. But as I have a B in the rule book it says you need to retain any safety that came with the gun. Trying to maximize what I got... If shadows were on the DOJ list in CA I wouldn't even of had this problem...... So if I had a 9mm 1911 I'd need to still have a functioing grip safety and so on. Youd need to keep the safety plunger in your glock and so on. E1.6 if you wanted the actual rule sited about the safety thing. The trigger is permitted in the allowed modifications for the class.

Czhase Posted March 18, 2014 Share Posted March 18, 2014 Yeah got to love that california list, but the FPB guns can be worked over pretty nicly. Link to comment Share on other sites More sharing options...

alma Posted March 18, 2014 Share Posted March 18, 2014 (edited) The CGW SRS 1 or SRS 2 include a modified lifter and firing pin to improve the FPB pull. I put one on my Compact L along with a type 2 Disconnector and it is 95% as good as my Shadow. http://cajungunworks.com/short_reset_system_-_srs.html Edited March 18, 2014 by alma Link to comment Share on other sites More sharing options...
JeffJ99 Posted March 18, 2014 Share Posted March 18, 2014 Are you allowed to swap out the hammer? I have a the SRS 1 + the type II disconnect as well as a milled shadow hammer on my 75BD and it's a nice single action Link to comment Share on other sites More sharing options...
