Brownell's pg 124, 125, & 6 have some 625JM/.45 ACP goodies. The moonclips I use are 5/$4.95 (965-065-005) on the first page, the nutdrver-style tool is $13.50 (352-197-000) on the next page, and, if you want to use .45 Auto Rims, the HKS #25M Speedloaders are $9.95 (392-100-025). Go to pg 154 and, since you reload - and can use Federal primers, order a Wolff reduced power hammer spring for $16.72 (080-665-210). I don't suggest a trigger return spring change for this revolver... it just feels mushy, even with the highest replacement strength spring, IMHO. Page 302 has the SDM fiber optic front sight replacement in red/green for $35 (864-000-003/004). Of course, proper cylinder and bore bronze brushes are a great boon, too... you probably have a selection of that. They offer better prices for a business or C&R ffl holder. Midway carries the same goodies, too.
One other note... mixed range-sweepings brass will work in a 1911/clone. Your new revolver treats your brass with more respect, ie, it doesn't 'throw it on the ground' - or ding it. Believe me, I hate to waste money, but buy your new revolver some new revolver-only brass... I like Starline. I have tried some beautiful one-use Fiocchi - and it's primer pockets must be a bit deeper, as they mostly had slight dings, indicating my fp was just seating them deeper. The new, and good, brass is important... a lesson learned the hard way... and Federal primers - now, no more ftf's!
Break-in your new 625JM with the OEM springs, but only after taking the sideplate off to clean/lube (They often. Repeat after break-in dry-firing 1,000-1,200+ times, installing that new reduced power hammer spring then, and leave it lightly lubed with a drop of a good gun oil on the axles, slide, etc. You'll love that revolver... and wonder what you should do with your lonely 1911's one day.
Oh yeah, my Dillon 550B only needed a new shellplate to load the .45 Auto Rims. I like 230gr FMJ (Berry's) over 4.5-4.8gr Titegroup for a comfortable 760-800 fps in either style case. I load 255gr LSWC (.45 Colt lead) over the same range of powder for 810-850 fps, pretty decent .45 Colt-ish loads - for hunting, etc. Some folks go up to 900-950 fps in a 625 with .45 AR, too... not me! You will have fun!

PS To 'try' .45 AR, Georgia Arms loads a 200gr JHP and 230gr LRN in new Starline brass reasonably.
