9 Ridiculous Rules About Beretta Firearms
The Beretta doesn't have an over-travel adjustment as a stock option. Having an over-travel stop is a problem for performance. Therefore, you will need to purchase a steel trigger to replace the plastic one (costs about $15). Drill a hole in the trigger as high up as is possible, tap it out for 6 x 32 tpi and install a set screw so that you've got an adjustable over-travel stop.
The M9 Beretta is one of the most well know pistols on earth, entering U.S. military service in the mid 80s. Because of its quality craftsmanship and high durability, it has the capability to fire under extreme heat and cold and even after being buried in mud, sand, snow and salt water. Add in a high capacity magazine along with a low recoil, it's easy to view why the M9 quickly became the standard sidearm for military personnel.
To be accurate for bullseye pistol shooting, the barrel must be match grade. Bar-Sto and KKM Precision both make good barrels for the Beretta Pistols (please click for source), and you'll get excellent results from just using a drop-in barrel. Contrary to common belief, there is no need to use a bushing at the front of the barrel to improve lock-up on a Beretta. The barrel locks up at the back against the slide using the locking block that is attached to the barrel, so it is crucial that your particular locking block is tight and in good condition. In case you are installing a barrel that will require fitting, you will be removing material from the back of the barrel until the gun shall go into battery reliably. Make certain and apply Dykem or any other layout fluid between removing material to view where the contact points are. You want as much contact as it can be between the back of the barrel and also the breech face on the slide. Some barrels (Bar-Sto) have extra material along with the back of the barrel and some of this must be removed slowly. The point of the extra material on these barrels is to get a tighter lockup with more contact surface, plus center the back of the barrel vertically on the breech face.
The UHC M9 features a spring pistol firing mechanism that allows its users to shoot as fast as they can cock the gun. This really is a good pistol in the event that you are just beginning to get into Airsoft or maybe if you just want to shoot some cans within your basement or backyard. You will enjoy hours of fun when you take down your targets with a deadly aim. On the contrary, for anyone who is already an avid Airsoft enthusiast, then the UHC M9 is a must have for your collection. In almost any case, this pistol delivers great performance at a very low price.
To improve lockup, some guns have set screws installed running up under the frame rails by the back of the barrel to give extra contact points while everything is locked in battery.
To improve service life, some gun builders modify the frame rails and replace sections of the aluminum rails with pieces of steel, affixed with screws. This really is only necessary in case you are a top level competitor and need that extra 2% performance that comes with a super tight frame-to-slide fit, plus the durability of steel on steel vs steel on aluminum. You can find no "kits" for doing this type of work, so you will need to have this sort of work produced by a person that knows what they're doing. This kind of improvement of slide-to-frame fit is similar in nature to the "Accu Rail" improvement that used to be done on 1911 style pistols.
Inevitably, sights. If you replace the rear sight through an over-sized adjustable sight, it really is common to need to trim down the very best of the firing pin blocker lifter to keep it from hitting the bottom of the sight. You'll also have to get a taller front sight. The front sight may be welded on (less common) or you can get one that slips over the stock front sight and pins in place (more common) or you may get the slide milled out with a dovetail (uncommon). Beretta makes an adjustable rear sight that allows you to keep the stock front sight and not have to modify the blocker lifter, but it really is more low-profile than most competitive shooters are going to want.
