You can swap a .357 sig barrel into most .40 cal glocks an vice versa and use same mags as all other parts and dimensions are same . Only thing I ever seen go wrong with a glock is in these two cals . Both have a tendency to break the edge off of the extractors . It will then sometimes not eject the round. I have seen new glocks do it and seen glocks go thru 1000s of rnds before it happened. Another thing which is a weak point in Glocks is the trigger return spring . It is a very little double hooked spring which pushes the trigger forward after every rnd. Every glock I have and have had as well as ever sold I replaced this part with what is called a 'New York' trigger which is a V shaped metal reinforced plastic spring . It comes it two weights of pull an 8lb and 10lb. Replacement of trigger spring will make your Glock last almost forever .

NY-1 Factory Glock trigger Olive 8.0 lb. : for Glock at GunBroker.com
This part will create a much better feeling and consistent trigger in a Glock .
Now the two glocks I want are the .380s that are only sold in Europe. The model 25 or 28 .
RedKat if you get a glock make sure to get a NY trigger for it as it will make it last much longer and be far more reliable . Takes less than one minute to install.
