HK P7 not grouping well
A while back, I purchased an HK p7, allegedly a grade A, with the expectation that it would be a very accurate shooter.
I shot it along with my nephew's Ruger 9mm, and as hard as this may be to believe, the P7 didn't group nearly as well as the Ruger. Some of the difference could be me not being accustomed to the squeeze cocker, but I can't believe it would make that much difference. A local gunsmith looked at it - he admitted that HK's weren't his specialty, but didn't see anything obviously wrong with it. He suggested I give the barrel a good cleaning to remove any metal fouling, which I did. I have tried both Remington & Winchester 115 gr. bullets, but am not satisfied. Is it possible that the barrel isn't broken in yet? I plan on shooting some different brands of ammo to see if that helps, but in the meantime does anyone have any ideas or suggestions of what may be going on with the pistol? |

What method are you using to test for accuracy? Sandbag rest, prone, free style, etc? Also when you say poor group size, what size and from what distance?

I was shooting both pistols offhand & didn't measure the group sizes, but the Ruger was shooting groups about 1/2 the size of the P7.
I will try to do more shooting Sunday and be more precise in describing the situation. Hopefully I haven't been premature in posting without the additional information. |

Problem most likely is the shooter not the handgun.... might not fit your hands right. I love my P7 but its certainly not everyone's cup of tea... but they are well regarded in the accuracy department. No offense to you.. I can't shoot a Glock to save my life... so I would guess its the shooter influencing the gun.

I would try some 9mm NATO 124gr bullets. My p7 prefers them over the 115

My P7M8 has always been extremely accurate. More accurate than a lot of larger guns.
When Dean Grennell and Wiley Clapp evaluated the P7s they were testing at 25 yards from bench rest and getting 2.75" groups with Winchester Silvertips and 3.25" with Federal 115gr Unless you fire from a bench rest I don't think you'll be able to draw any conclusions. |

If you decide you don't want that P7, I'll take it off your hands, cheap.

The cocking of the gun is part of the accuracy- it takes some force to cock it but almost half to keep it cocked. Try letting up on the grip to take the additional fatigue off your hands which will cause your hands/arms to shake & be sure to maintain a full grip at all times. The trigger has the length of travel between a Glock and a 1911. It breaks clean like a 1911 but there is more travel so you need to make sure that the pad of your finger is set up so that it's movement does not bring your gun off target. You also need to make sure that your movement is consistent. Have you tried dry firing to see if you are jerking the trigger or anticipating recoil?
The P7 is a rare bird in the fact it ranks among the most accurate handguns in the world but with its short sight radius and unique mechanicals, it will be ruthlessly revealing of any flaws the user inputs. Try thinking of the gun as a fine surgeons scalpel rather than a knife. Hope this helps. |

As to the OP's P7, I suggest having someone else, who you know to be a good shot, shoot it. Try a variety of ammo as well. Quote:

The pistol has a barrel rigidly attached to the frame which makes for easy accuracy. Mine gave 1.25" groups from a rest at 25 yds - not unusual for P7s !! I does have a rather short sight radius though. The trigger is excellent near 4 lbs .

Its not always the shooter.
With a quality made fixed barrel you should get at least 1 inch groups. Have an Interarms PPK that was giving me 4-5 inch groups. Couldn't believe it. Gun was pristine with a beautiful barrel. But my early 1930s PPK was giving me 1 inch groups. Finally, re-barreled it with a new barrel...and it shoots as well as my older PPK. Have 2 new identical Romanian TT-33s, one shoots 1 inch groups and the other shoots 4 inch groups, you can guess which is the carry gun and which is the parts gun. Had an S&W 29, etc. etc. Sold it. I collect Walther M4s, the prettiest one shoots the worst, but I keep it because its beautiful and has documented WW1 history. If you can get your hands on another P7 you will find out pretty quick where the problem is. Its not always the shooter.

I agree it is not always the shooter as well. But it would help you along to shoot from a sandbag rest. Even when I shoot a poor group from a sandbag I have a pretty good idea if it was me or the gun.

If I'm shooting poorly with my P7, I know it's my fault.

When Dean Grennell and Wiley Clapp evaluated the P7s they were getting 2.00" groups with their handloads.

The P7 is one of THE most accurate pistols ever produced. I don't know how you can judge anything based on how you "tested" it. Barrel broken in? Come on now. |

I appreciate all the comments - I will try shooting from a bench with some different brands, and pay more attention to my grip.
If that doesn't work out, I will get with someone that also has a P7. That should quickly reveal if the problem is with the gun or the shooter. |

"I shot it along with my nephew's Ruger 9mm." [Boydster]
Sounds like a fair test to me. I have a simple rule, if a gun shoots accurately for me in that first mag (or cylinder) I keep it. If not, I sell or trade it. Life is too short to 'learn' how to shoot a particular gun. I prefer a natural shooter. You wanna hang onto that Ruger.

My P7 shoots 115gr just fine, but it was optimized for 124 NATO.
I know it is an "A-Grade" but did you buy it straight from a retailer (not consignment) or a private individual? It might have come in the country as an A-Grade, but use over time might have worn a few things. I replaced almost all the springs on mine when I had it refinished, but that was for reliability not accuracy.

try shooting the p7 without really aiming. just point your arm. that's where the p7 shines. go from low ready, pull up, and fire when it feels right. you will be amazed. it's a combat weapon, not a range gun.

While I agree the P7 is a great combat handgun. Low felt recoil, little muzzle rise, great trigger, instinctively points, it is also a VERY ACCURATE aimed range gun. It is right up there with my longer barrelled centerfire handguns in 9MM, like my BHP, and CZ-75's.
There is either something terribly wrong with the OP's P7 or he is not shooting it properly.

I would not imagine it being the gun. It may just be how the shooter interacts with that specific weapon. For some reason I am more accurate with some handguns than with others. A different shooter with the same guns might have different results. For the most part my P7's have been some of the most accurate of my guns, for me. I shoot my Glock 26 more accurate than my Glock 34. My 92fs more accurate than the P9s .45. My P7 PSP better than my P7m8 and so on.
