No, no, no - you must get a Glock!
To clarify, I do think the .45 has more "stopping power" than 9mm. However, I think the difference is marginal enough that it doesn't outweigh the 9mm's advantages in ease of shooting and economy. Anyway, a shotgun beats either!
Well, it's not what I'd choose for a pure range gun, but pretty much any gun can be a plinker. Just choose what you like. If the X-five floats your boat more than the others, go for it. I'm not sure what the other two guns can do that the X-five can't, in terms of poking holes in paper.Do you guys think one X-five can realistically replace both? Or, at the end of the day, is it just another fine gun that would deliver no more accuracy and fun than either the P30 and/or Supermatch.
However, if the point is just fun at the range, you might consider a wider variety of guns. Some folks like to shoot lots of different guns versus one really nice one. $1600 will get you a decent .22, 9mm and a .45 if you shop carefully!
