What do you use in the competitions? Caliber, model, competition type, reason???
For USPSA, I usually use a bone-stock Smith & Wesson M&P 9mm - because it is what I carry.
I also use it in IDPA.
In the past, I have used a .45 Smith & Wesson revolver, model 625 for USPSA's revolver division & for ICORE when it was around here.
For Limited division, I have used a CZ "Standard IPSC" aka Tactical Sports in .40 cal and also I have used STIs or SVs in both 40 and 45.
I started shooting USPSA with a Glock 19. Used it for steel shooting too. I hjave also used Glock 17 (also for GSSF shooting) and CZs - particularly an SP-01 and an 85 Combat.
When they used to shoot bowling pins in MD at Continental and Deep Run (both now gone) I used a Model 19 in 357 magnum, or the Glock 19. For .22 I used a MK II ruger. Shot pisn once at the range they have set up down in the basement of the NRA's HQ off Rt. 66 - I used a .45 cal CZ.
Where are you guys shooting the 3 gun matches?
