Help understanding

[PWC]

A longgunner asks please:
Handguns...what is a good small concealable DA/SA revolver, .38 to .44 cal, 3" +/- bbl with xposed hammer? Don't understand the alphabetical sizing...j k l m

Derringer = belly gun no matter the cal. (nope)

What revolver fits the size of an open hand kinda like the Walther PP series?

Next up pocket or pocket holster? (I know, I know, hammer or nub for S/A)

What are the alphabet sizes, small to large, with the below considerations/reccommdation for each.
Cals?
IWB or OWB comfort?
Concealability?

Lotta real estate here.

I will open with the alphabet you posted. Not into Colts much and new/newer stock has been out of production for some time now.

S&W J frame (small) 22's, 32 Long, 38 special.
S&W K and L frame (medium) 22's, 32's, 38 specials and 357's.
S&W N frame (large) 357's, 41mag, 44 special, 44mag.

Only the J frame with a 2" barrel would probably fit in the palm. An exception would be a S&W 19 or 66 (K frame) with the 2 1/2" barrel. Newer models are out that I no longer keep up with.

I personally like the Rossi model 88's SS with a 2" barrel. They are very similar to the old S&W model 60's (J frame). I have bought a couple of Taurus 85's too (Rossi sold out to Taurus).

All I did here was open a can of worms. Hopefully some of your questions were answered and other folks will comment further.

Allen, thank you for 'splaining the alphabet guns. Didn't think there 'd be such overlap in cals. I only used my palm as a frame of ref.
