az paul, here are a couple of suggestions that may help you attain tighter groups with your UZI Pistol:
1. If your shots are all over the paper and grouping no where near the point of aim, this pistol just may be too heavy for the type of hold you are using. You really didn't give me much info about your personal shooting style and specifics but with a gun of this size you must have a strong stance to support the weapon. Some shooters flinch and try to "help" the bullet down range, I find the UZI's weight actually lessens felt recoil !!
2. You mentioned that you have no problem with more conventional hand held pistols/revolvers. This in and of itself tells me that it may be a weight/size issue. My UZI Pistol has common everyday 3/dot sites just like the majority of weapons in use have so I don't believe it is an issue to do with the sites.
3. Do you seem to shoot better when it is set up with 9mm rather than when it is set up for .45acp ? IOW, does the lighter caliber make any difference at all in the accuracy of your shooting ? Have you tried shooting 9mm with a partial magazine to minimize weight ?
4. Have you tried shooting close targets such as 5-7 yrds ? Consider shooting alone a time or two or more to limit distractions while you are trying these new things. Shooting with buddies and or family is great but sometimes it becomes a big lead burning session rather than seriously ironing out some wrinkles in your technique. If you can concentrate in a crowd, go for it, by all means. Consider the importance of hand positioning on the weapon, strong hand firmly over the grip safety, trigger finger outside the trigger guard, pointing forward, 3 fingers around front of grip. DO NOT STRANGLE THE GRIP. Weak hand fingers locked ontop of strong hand fingers, thumb forward or locked on other thumb if preferred.
5. As I alluded to in #1 you must have an good rigid body and arm structure to hold a weapon of the UZI Pistols weight yet not so rigid that it makes you shake or flinch. If you prefer the Weaver two hand stance, take a few moments to go over each feature in the stance and make any adjustments you think may be necessary to improve your overall accuracy with the weight of the UZI. Foot placement, knees bent, weight distribution on your feet. You see, on paper, the UZI Pistol is like any other pistol in the world. Pick it up and everything changes. It may be necessary to find a work-out routine that strengthens your upper body until you are comfortable and capable of tight groups. These are all suggestions, some of which may help and others that may not.
6. Make sure you are using ammo that you know groups well. Don't try to shoot the 10 ring with UNproven ammo (cheap reloads). I am sure you have a shooting buddy who is consistantly accurate with all his or her weapons...can you think of one? Have them shoot a magazine of 9mm and a mag of 45acp and see how they do. This act would be fun for them and you, (Everybody likes to be able to say they have shot an UZI) but it's main purpose is to check the accuracy and functioning of your pistol, HECK, take a picture of them shooting it, they will want to pin it on the wall of their cubicle at work ! If your pistol is deffective, we want to know ASAP before all your hair is pulled out.
Well there we go...just a few things to consider. I can think of a number of other things to try but we will save those for next time, IF there is a next time. Happy shooting and please let us know how things are coming along with your next shooting sessions. We are happy to help anytime, just ask. Best Regards, JIMBO
