As a rule, for a carry gun, if it hurts to shoot less than 5 consecutive shots, I don't want it. Reason being, I won't train with it, since I won't want to shoot it. That means most ultralight (scandium/titanium) J-Frames, LCP (and similar sized guns), etc are a no go for me. Smallest gun I own is an LCR, and it's actually really nice to shoot. +P is a bit uncomfortable to shoot with it, but not painful.
Definitely agree with this. That's why in my thread that's active right now I denied the idea of those guns.
They make the range unpleasant therefore, I won't train with them as much, which in turn will make me feel inadequate to carry a gun like that.
Sáncte Míchael Archángele, defénde nos in proélio, cóntra nequítiam et insídias diáboli ésto præsídium. Ímperet ílli Déus, súpplices deprecámur: tuque, prínceps milítiæ cæléstis, Sátanam aliósque spíritus malígnos, qui ad perditiónem animárum pervagántur in múndo, divína virtúte, in inférnum detrúde.
