Jeremiah- not intended as a slam, but sharing information-
When you fire a handgun, the slide will BRISKLY be driven to the rear by recoil. However, it was designed so that a given WEIGHT of parts is recoiling. Start changing that, and you may or may not affect the funtioning of the pistol.
Second point- the gasses that drive the bullet are set free at the muzzle- and exit the muzzle at several thousand PSI. They do not just go straight ahead- they also go out to the sides of the muzzle. Anything in the path of those gasses will not only be destroyed, but probably turned into a projectile.
Please- before you start adding this and that- take the time to learn about the basic machine you are buying. The suggestion to download the owner''s manual ahead of time was a very good one- gives you a chance to figure out what questions you still have after reading them.
Also, if you have not yet acquired them- you should not shoot without eye protection, and hearing protection. Unless you want to be like us old farts that have irreversible hearing loss, and spend a lot of time saying "What?". If you don't already have some, and if money is tight, find a Harbor Freight store. Yellow tinted safety glasses are a couple of bucks, ear muff type hearing protectors about $5. Every issue of Popular Science and The American Rifleman has a coupon for 20% off one item in the store. Go get some.
What we have here is... failure- to communicate.
