I was sorta looking over my pistol inventory when I realized I had "pairs" of pistols....that is the same gun in at least two sizes...like big and small, short and tall. Didn't do it with malice of forethought...but it just seemed to work out that way. I bought a Beretta PX 4 in compact, liked it and got a full size. Or got a Walther 99AS and decided the compact would be great to carry. Here's the list: S&W M&P 2.0 5" and Shield. S&W 5906 and 6906 Walther P1 and P4 Walther 99AS and P99ASc Sig 226 and P6 (a bit of a stretch, but I sold my P229) Beretta PX4 and PX4c 9mm 1911 Colt Gov't. competition and Star BM (another bit of a stretch, but at least "cousins.") And both Sig 320 and 250 with different size grip modules in compact and subcompact sizes. Wondering if anyone else is either deliberately collecting "pairs" or even triplets (full, compact, subcompact) or has found out it just sorta worked out that way. What I don't have a smaller or larger versions of is: my BHPs, CZ75 Omega, Beretta 92FS, or my S&W 39-2, although I'm looking for a hot deal on a 3913 or 908.
