.40 or .45 for single stack?

[honda01]

I shoot both the .40 and .45 for IDPA and for USPSA-single stack. For reloading the .40 I have found that loading long...ie. 1.18 helps the .40 feed better. I also use 10mm mags for mine. For IDPA -shooting ESP you can drop the power factor down down to 125 which would be the minimum for scoring minor in USPSA. If that is what you want to shoot is minor..there are those that may argue that you might as well shoot a 9mm. As previously mentioned above, recoil is only what you perceive it to be.

Go with the 40. To many advantages and no disadvantages that I know of. Ive owned one for 12 yrs or more. Load it to about 1.220" in 10 mm mags. Never an issue here.

I guess that's what I'm trying to figure out....what are the many advantages? From everything I've heard, and have seen posted it comes out about even...

Mick said: I do like the 230 grain bullet over CLAYS better than the 180 over N320 despite over 300,000 rounds of the 40.

Same here, so I went with slower powders with the 180gr in 40S&W and found several combinations I like better. Power Pistol, HS6, and W571 (obsolete but equal to the old HS7 so it's a bit slower than HS6). The gun handles differently, no doubt about it, but I shoot higher hits when I shoot the 40 and 45 back-to-back in the same course of fire.
