    Ok so I picked up a gen4 G21 frame off GB. I want to do a custom build for target shooting Let’s hear some recommendations on barrels and ported slides. Either cut for a RMR or I can get it cut.

    I’ve used a KKM barrel in my Gen3 21 for years and like it a lot. No other major mods to my 21.

    If you want a close to 1911 barrel fit get a Barsto barrel that is semi fit. Requires little fitting which you can do with stones. Then you'll have a far more accurate barrel than a drop in. But I have a KKM drop in which is decent.

    And you don’t need to be a gunsmith. They give you directions and very little material needs to be removed

    I know Lone Wolf makes decent slides. Some pre-ported. Others cut to order. I bought one for my Glock 20 with a bull nose and a six inch ported barrel with a cutaway on top of the slide. Looks good.

    Scott you can also get a Barsto barrel that’s ported for a G21.

    Also, get yourself the GI .50 cal conversion.
