Funny you'd say that... we picked up a 42 for my wife because she doesn't shoot the 43 too well. Now the 43 is all mine
Honestly, though, the 45 has no appeal for me, and neither does the 19X. But I will admit I'm being drawn more to a G19.5 as time goes on. Maybe that's what I'll do with the GSSF coupon when I register for the local match...
