The P94 is quit a bit larger than a 669.
The 669 is just the stainless steel version of the 469.
I'm assuming the 669 frame is also stainless - so the 669 may be a smidgen heavier than the alloy-frame 469.
I have a 469. Its about the size of the "baby" Glock.
The double-action trigger is typical Crunchenticker. Insanely-long pull for a first-shot double-action. Your target better be close.
The 469 is a cool 80's gun. I like to carry it when I'm wearing my Leisure Suit and mullet toupée.
The P94 trigger is probably very much like the P95 trigger, of which I've had four. Pretty much the same trigger issues as all the other Crunchentickers.
My thoughts on the P94 are "belt and suspenders" - as in its so heavy, you will need both to hold it up.
I got my 469 used. Very gritty trigger.
I blasted it with Break-Free, and compressed air, and detail-cleaned everything, and the grittiness was cured.
The Smith and Wesson 1st, 2nd, and 3rd generation guns all use the "trigger bar" concept, which is two long, fat pieces of metal sliding against the frame of the pistol and the magazine. A less-than-ingenious design for sure. Dirty ammo (isn't it all) gets the trigger bar dirty, and the "gritty" feeling is unavoidable unless you meticulously clean the pistol after each outing.
