My LCP w CT is very, very accurate. W genuine Ruger clips, it goes bang every single time from lead reloads, to Golden Saber 102 gr HP to Critical Defense 90 gr.
The LC9 is slightly bigger and cheaper to shoot. but LCP is 9.4 oz vs close to 16 oz in LC9 and this is before the weight of ammo.
Only thing smaller is the 22 LR/22 Mag pistols. You'll have to operate a hammer under stress is the only drawback.
