Hey all question i have a glock 20 with 4 hicaps and was at a local gunshow when a glock armor told me i could buy a 357 sig barrel and a 40 barrel and have 3 guns in one is this all true without any mod to the gun or is this a snow job to sell me more stuff. I also wonder if i did the right thing i had marine cups put on my 20 did i waste my money

    What he told you is true. They are all based on the 10mm cartridge and therefore use the same extractor and mags. Do you plan on doing a lot of shooting underwater? I understand that's what the marine cups are for.
    Without the NRA, the second ammendment would already be gone!

    Yes, you can switch barrels and use the same mags although the 357 and 40 cases are a little shorter they are all 10mm in dia. You do not have to buy them from Glock as there are many aftermarket available.

    well lol no i dont do alot of underwater shooting nor do i plan to but if it ever came to it i was hoping i would be able to but later found out that the cups were only for the modle 17 T or F and that if i shot my 20 under water it would likly blow up when looking on the glockmeister page i think he makes a reference to the 17 and only with flat point bullets no other model was referenced too

    The marine cups are used for underwater shooting. The Navy Seals use them in all their Glocks. A Seal told me if you want to go deaf then shoot your gun underwater.
