The Remington R 51 sure has got my attention, might make room for something a little different.
Had you asked this a week ago, I'd have said
#1 - SW M&P 9mm (full sized)
#2 - G42 (maybe, still havent fondled one)
#3 - G19 gen 3 - just because I don't have one.
So I went to the shop to fondle the 42 Saturday. Ended up scoring a custom 1911 that came out of nowhere. Go figure, it always seems to work like that.
That always happens to me. I'm always looking for a larger gun safe!
Probably a Ruger SR-22. Eventually I'd like a .45 as well.
I have a G 19 and the plan is to add a G 17 to the collection. Keep the 19 for EDC and the 17 for HD/SHTF type stuff.
