I hope this is in the right place, but if it isn't please just let me know. I have a Sig 1911 Extreme that I currently carry as my duty weapon. It has all Wilson Combat fire control group that Crawley Customs in Texas fitted for me. I am currently running a 17lbs Wilson Combat flat recoil spring (ISMI?) w/ GI Guide rod, 21lbs mainspring (factory Sig), and a Harrison Design firing pin stop. Currently has a consistent 3.75lbs trigger pull. My issued/carry ammo is Federal HST 230gr +P.
I already dabble a little in some heavy 45 colt loads in my Ruger Blackhawk and have been wanting to dabble a little in some heavy .45 acp loads (450 SMC or 45 Super). I have been curious about this for a while, but have started to research heavily the last couple weeks and have been unable to get a clear and concise answer on mainspring weights. I do not want to run a super heavy recoil spring for battering and general recoil impulse upon lockup, if I can avoid it.
So where should I start on mainspring weights? I was thinking about ordering a 26lbs, 28lbs, and a 34lbs from Wolff and once I figure what will work, ordering a couple three packs. I know it could increase my trigger pull slightly, but I am not too concerned with that unless it goes over 4.5lbs. I have read a lot of negatives about using shokbufs, but should I consider using them in this application (only with 450 SMC or 45 Super, not on duty)? I have also read mixed reviews of shooting 45 super in a standard non-ramped barrel. Is this a legitimate problem or is this one of those situations where you would just check spent casings for bulges in the case head? Anything else I should keep in mind?
Thanks for y'alls help,
Clay
