I'd bet it's a
little bouncier on firing if your Slimline is a small-magazine type. Anything as big as the 17 or the 20-odds will have that much more bullet mass to soak up the acceleration, with the heavier weight of a magazine of .40 or .45 bullets being noticeable. You might notice the slide cycles faster -- I've noticed that about some 9mms versus my .45 1911 types. Everything would get done a hair quicker.
You can get pistol competition things like PAST gloves to help with recoil owie during practice sessions. While you wouldn't lumber yourself with these during carry-use, they'd make for comfort while you get your marksmanship refined to whatever degree you want to afford. Then a little practice barehanded, as you carry, to iron out any differences of pointing or feel, and you're all kinds of ready.
Glock 36 -- 6 rd magazine, 765 grams fully loaded, over a pound and a half. The lighter slide means less perceived recoil than the bigger 1911 type pistols, part of whose kick is really the feel of a fairly massive slide going back and forth.
Aliantha, I'll assume from your smiley that you're being completely facetious. However, seriously now, you've reversed cause and effect: when I hoist the banner of self defense, guess who or what crawls out of the woodwork? We have seen the hoplophobic neurosis on extensive display from Spexxvet. The people who are sane, and knowledgeable, on self defense do
not fight me.
