Glock 38?
 

i have recently purchased a glock 38 .45 doing some research it seems like they dnt have really any upgrades for this glock besides a lazer or light or night sights.......does any 1 know if they make a aftermarket barrel for this weapon??? or for that matter anything custom

If you can't find it here, you don't need it:

That being said, the only things I personally would add would be a good set of sights and the Glock slidestop off the G34/G35.

It's not a 1911. It does not need any "upgrades". Aftermarket parts are the biggest single reason for a Glock to develope reliability issues. It is best left alone, other than adding night sights...
