There isn't a per-say list of acceptable pistols for the 1500 semi-auto. Ditto
for the 600 Distinguished pistol.
The S&W 52 and other Colt 1911 - .38 Wadcutter pistols are disallowed on the
basis of ammunition - no full wadcutters in the 600 Distinguished pistol match. Besides,
these pistols have to be hacked to take 6 rounds in their mags. Rules descibing what
is permitted in a 600 Distinguished Pistol are in CPCA rule section 3.4.
There is no ammo restriction for the 1500 Open or 1500 Pistol, so these wad cutter
pistols are ok. See CPCA Rule 3.3 - Any centrefire pistol.
Each CPCA member has 3 separate classifcations now:
Revolver, Pistol, and Duty. You will have to consult the match flyer to see
how the matches are setup. There is a lot of shooting fun if you go to a full
match. 150 Revolver /150 Pistol /150 Duty /60 DP/60 DR/60 snub -
690 rounds, 6 firearms and their associated holsters/mags etc...
Any holster which covers the trigger guard is good to go with traditional PPC.
The CPCA 1500 Duty Pistol match isn't considered traditional PPC. This
style/course of fire is not descibed or shot by the NRA.
There is a list of acceptable firearms for the CPCA 1500 Duty Pistol match.
This match doesn't follow NRA PPC rules. It has its own rules section in the
CPCA rule book - L2 or greater retention holster and two full retention
magazine holders and limited list of "duty" pistols with 5lb DA/Striker
triggers. No SA permitted. 4 magazine are permitted and can be fully
charged (no 6 round limit), if you are LEO using work gear, you get to use
fullly charged hi cap mags.
