First, no 10mm/.40 experience here. But - lots of .45 ACP (625) and .38/.357M (x8 627's). I like Ranch Products moonclips. The blued steel ones are all you need there - and I believe my last 625 .45 ACP x6 size were $35/100 delivered, while the 627 .38/.357M x8 size were $50/50 or $75/100 delivered. Both calibers load easily by hand with Starline and Remington brass. They strip easily with the $16 nutdriver-styled demooners like Brownell's sells. Check with them for current prices.
