As has already been mentioned there are several different lengths of 45 ACP cylinder for the 625s. I think I have seen three.
45 SUPER is just fine with the 625s modern metallurgy. I would never fire 45 SUPER in the older model 25s. I have been shooting 45 SUPER from my 625s for probably 15 years now. I would not load to 45SUPER pressure in standard 45 ACP brass. If you plan on using the 45 SUPER order up some brass for it.
I move the Speer 260 JHPs out of my guns at 1000+ depending on which firearm. I get about 1100 out of the Springfield or the long USP.
The 230 JHPs move at over 1200 from the 625s
