No Safety At All
If you are looking at a pistol, do you mean it does not have a manuel safety or a SLICKSLIDE model without any switches, levers or gadgets.
The I&NS used to require that private purchase pistols not have any slide mounted safety.
I have used the BERETTA 92D Centurion which has a shorter barrel and slide than the standard size 92 model and the 92DCM which is the the same short barrel and slide combined with a shortened grip and single collumn magazine. They both shoot very well for me, but are not as small as the guns you mentioned.
I like the DOUBLE ACTION ONLY pistols without any safety lever. The BERETTA pistols have a very smooth action. Some are even better than a SMITH & WESSON with a street (smoothed, but not lightened) trigger job.
The other option would be a SAFE ACTION pistol like the GLOCK which does not have any safety lever either.
