How many lumens for an indoor weapon light?

Do these work with u notch? I've got three u notch most likely gen 1. One has a +1 and one has a +2 I believe. Probably been like that for almost 30 years.

You need the full metal lining of square-notch mags if you're adding an extended baseplate, otherwise the extra spring tension causes the all-plastic frame of a U-notch mag to buckle and pop the extension off. At least that's what the base plate manufacturer told me and I didn't want to risk trying otherwise.

Probably not, only use square notch magazines.

Hmm I'll have to figure out which ones are on my mags. Definitely u-notch and my dad used them with his gen 1 Glock 17 for years and years.
