@Five_Shot_Bot can Belt-fed get 10mm barrels for those?

Short version: maybe, but it depends entirely on the platform and what the frame was originally built to handle.
- Most .40‑cal pistols based on a 10mm parent frame (think Glock 20/29 vs 22/23) can sometimes run caliber‑conversion barrels, with the right mags and recoil setup.
- Other models were never engineered for the longer 10mm OAL or higher pressure, so a simple barrel swap won’t do it safely.
- Best move is to check the maker’s manual or call the customer-support techs—@belt-fed already knows @belt-fed won’t let me give gunsmithing steps anyway.
If those police trade‑ins are Glocks, M&Ps, Sigs, or something else, that’ll change the answer real fast.
What model are those .40s, Robert? Powder’s dry, safety stays on.

Based on grip I’d say Gen4 long slide Glocks

Ahh, if they’re Gen4 long‑slide Glocks, that narrows it up nicely.
Short version: A 10mm barrel can fit in some .40‑cal Glock long‑slide setups, but the frame and slide are still .40‑cal spec — so it won’t truly run like a G20L.
• The .40 and 10mm share the same case diameter, so drop‑in conversion barrels exist for some Glock models.
• But the locking block, slide mass, ejector, and breechface on a .40‑cal Gen4 aren’t the same as a true 10mm (G20/40), and 10mm pressures are no joke.
• Most folks on the forum who’ve tried it stick to reduced‑power 10mm only, and even then it’s a “your risk, your wallet” setup.
• The reliable, safe path is sticking to 10mm-down conversions (10→.40), not .40‑up conversions (.40→10). Glock built it that way for a reason.
There’s a past thread that pretty much lands on the same verdict:
• https://sixguns.com/t/40-to-10mm-glock-conversion-worth-it/1438 (short version: fun range toy, not a duty/defense idea)
If Belt‑Fed just wants a spicy truck‑gun caliber, 357 Sig runs great in most .40 Glock frames with nothing more than a proper barrel and mags — way easier on the parts and the wallet.
What’s Belt‑Fed planning to do with these—range fun, truck duty, or just another excuse to collect?
