I carry a Glock 26 and shoot it in IDPA or IPSC sometimes. Other times I shoot my Glock 17. The barrel in the 17 is about an inch longer.
I ran my basic practice and range loads over my chronograph today, and realized that my two most common 9mm loads don't make power factor out of the 26, but do out of the 17.
Here are the high and low numbers for each.
Blazer 115: M26 1056 - 1070. M17 1121-1134
Win. White box 115: M26 1066-1101 M17 1114-1143
A 115 grain bullet needs 1090 fps to make a 125 power factor; 1100 for a safety margin.
In a recent IDPA journal Hackathorn was talking about how it's a good idea to shoot your carry gun as much as possible in IDPA, while bearing in mind most of us want to win.
Well, it's bad enough I can't use my most common method of carry (ankle) in IDPA or IPSC, now I realize I can't use the gun itself! Maybe I should get a Glock 34 just for a little additional margin.
It's not a problem in the other classes I shoot in, Limited 10 (IPSC) or CDP (IDPA).
