Sig is so confusing with their P320 Nomenclature - I'm speaking 9/40/357 (but my references are to 9mm capacity here) as the 45 is different frame and slides
Subcompact - 12+1, shortest grip and slide
Compact - 15+1 (most similar to Glock 19), obviously a bit heigher in grip and longer in slide than Sub
Full Size - 17+1 (most similar to Glock 17), longest slide length and grip height
"Carry" is the bastard child, is the Full Size grip HEIGHT and 17 round capacity, with the shorter Compact slide length - which makes no sense for Carry purposes as the grip height sticks out the most -
And then you want your mind blown, when the P320 first came out the dealers were calling the "Compact" the "Carry" and Sig had to correct them but it still confuses people - basically if you have full slide and 17 rounds its a Full, shorter slide and 17 rounds a Carry, shorter slide and 15 rounds a Compact, and shortest slide and grip a Subcompact -
Does that make sense and help better
- On the Gen 3 G17 I agree, you'd need man sized gorilla hands as the Gen 3's are thicker pistols out of the box, no backstrap capability, different grip texture (the Gen4 is much improved) - I'm hoping that Glock discontinues the Gen3's soon as they have been around for almost 20 years, and when the newer Gen5/ "M" models come out eventually they Gen4 will be the "new Gen3" so to speak -
