Thanks for the replies! I would not want to get screwed with bad warranties.
Yes, the $100 rebate on Walther products right now does bring them down considerably. I can get the 5" PPQ M2 for just over $600 that way, and it's the same as the Q5 minus a few "pieces of flair" (anyone remember Office Space?
) and the ability to mount a red dot.
I also have an XD Mod.2 3" and have thought about getting the 5" tactical model. It's quite a bit heavier than either the Walther or Canik--not specifically a competition gun, but I already have magazines and accessories for that gun, as well as night sights I could take off the existing gun. So the Mod.2 Tactical represents my lowest-risk, lowest-cost option overall. For $150 I can get a competition trigger kit installed. I've tried someone else's gun with that mod, and it does put the trigger feel into Walther territory.
Someone said 'for competition, heavier is better.' That makes sense for recoil purposes...
But then, why do all the competition-oriented striker guns come with a bunch of cuts in the slides and other features specifically to reduce weight? Glock, Walther, S&W, etc. all cut down on weight for their "competition ready" pistols.
