It lead me to search out a 245 nib. GB had one for 600.00.
Seems I could outshoot all my other guns with this one! It accepts 220, seven and eight round mags. The little finger curl disappears with these bigger mags, but it is very easy to get used to it. 15 rounds total with an 8 round mag change. Best gun I EVER bought!
IIRC the 200 carry simply has a longer beaver tail than the 245.
I do love to carry a 239, but find I carry this more often now. 245 is a bit fatter than the 239, otherwise similar profile except the squared trigger guard.
45 never shrinks, is a lighter push rather than a snap on recoil, is heavier because of the 230 grain slugs. Seems to give me that warm fuzzy feeling all over.
