I own a 19 and 23 and thinking about what to purchase with next years GSSF coupon. Is the Glock 38 frame an exact duplicate of the 19/23 frame excluding ejector and maybe locking block? Is it hard to load the 8th round in to the magazine or is there a little free space, unlike the 19 and 23 mags? Thanks Wanna kill these ads? We can help!
