Well i can tell the the Compact 941 Jericho 9mm ends at looking gorgeous!! I recently used the pistol for 2 months as it was issued by the company as a PPW. Let me list the disadvantages:-
1.It is about as compact as having a brick in a holster.
2.The top slide is a lot thinner than an average pistol so making ready can be quite difficult.
3. The slide locking lever is to far forward to lock the working parts to the rear, without moving the pistol in your hand to gain purchase.
4. Trigger is weak and slow, causing problems when trying to double tap...even with good ammunition.
5. It wieghs over a kilo aswell
So if i were you i would leave it in the gun cabinet in the gun shop looking gorgeous, where it belongs!!
As the guys above have mentioned the Sig 226 is one hell of a pistol, and so is the HK USP, i can vouch for them as i have used them both.
However where i live and work at the moment concealability is the name of the game, i was going to go for the Glock 19 as again i am familiar with its operation, this is classed a compact pistol but i recently used the Glock 26 which is a Sub-compact pistol which again chambers a 9mm round.
The model i fired had been upgraded with a new compensator, which increased muzzle velocity and decreased the barrel rise considerably allowing a very close 2 round group on the double tap.
Also after a bit of investigation i found that due the the frame of the pistol been the same as the 17/19 you are able to fit either the 15 or 17 round magazine, although you will have to fit an adaptor to the magazine, as the standard issue magazine the 26 comes with forms part of the actual grip.
I also carry as back up a Walther P22, again a very compact pistol, one slight disadvantage though it is .22 which doesnt have much stopping power, but used in the right way can lead to the target dropping just as well as a 9mm or .45.
