You have a Smith and Wesson model 14 38 special. The 38 refers to the diameter of the barrel. That barrel is 38/100 of an inch in diameter. A 45 automatic has a barrel that is 45/100 of an inch in diameter. A 9mm has a barrel with a 9mm diameter. You can shoot 9mm ammunition from a 38 special. A 22 pistol has a small diameter barrel.
50-350 USD or so
No. The 9mm is not compatible with the .40 caliber frame/slide. On the other hand, you can put a .357 SIG barrel into a Glock 22 and use your .40 magazines.
The model number should be stamped on the barrel just above the trigger guard.

Need model number or style. Most likely this is an FN gun in the Hi-Power line of 9mm. The barrel should tell you the caliber.

No. Some .40/.357 Sig pistols can be converted to fire 9mm simply by dropping in a 9mm barrel and using the 9mm magazines, though. Not sure about the Glock.
