Greetings Everyone! I'm thinking of buying a Glock 26 to supplement the Glock 17 I already have, but I am also looking for an extended barrel for the G-26 that has length of over 4.2in. and less than 5in. - to replace the factory supplied one. Is there such a thing? Don't laugh... I've never looked into barrels before so I need your expert advice. ^2 Your help is welcome and appreiated! BTW, if there is something like that, when I order it do they stamp the serial number of the gun on the barrel or do they stamp some other serial number (or none at all)? Thank you!
