Original Mod 6M

[andyals]

Can anyone here give me some info on this pistol.
Specifically, performance, reliability etc.
I know it's no match for a modern pre charged but it might do me and it's much cheaper.

There's an article here : http://www.network54.com/Forum/67020...iginal+6M+test which contains some info, and the Forum proper contains other snippets if you do a search. As an aside, the original piston heads are prone to failure and can be expensive to replace due to the complexity of the pistol. If you are thinking about buying it, it might be worth while finding out something out about its service history.

HTH, Vic Thompson.

I have a 6G as I prefer the lines.

I had mine resealed by Lawrie, and it functions beautifully.

Relatively easy to cock and very consistent.

Mine likes R10s, and will put pellets through the same hole at 6 yards, only tried this bench rested, I'm not that good!

A pistol well worth owning. It you can get it for the right price you won't regret it.

Kind regards,



Phil

The model 6 uses the same internals as the model 10 both having twin reciprocating pistons but different trigger parts.
The 6m has the barrel sleeve from the 10 but 6g does not.
Early guns with the original seals that revert will either have failed by now & been replaced or will fail very soon.
Guns with seals made after about 1985 will probably be okay even today, they are that reliable & probably out last the springs which have been known to go for twenty plus years with constant use, springs are very high quality.
The model 6`s are easier to strip than the model 10 but neither are rocket science but you will need a spring compressor.
Sometimes the cog covers can be a bit tricky to remove without damage but other than that easy!
Reliability is excellent.

Thanks for the replies.
I just need a cheap way back into target shooting, and was horrified to see the cost of modern hardware.
I'm picking up the pistol on Sat.
I'm, sure it'll be OK for me till I find my feet again.

They're great pistols, the 6, the 10, great GISS system
Only downside is, that he GISS system is quite easily ruined if abused..(pinion caps, pinion threads..).
So if you find 1:
- make sure it has new seals as said above
- check the caps for damage, check their fitting is original
- testfire, make sure the caps stay in place

...and finally, make sure it has a straight barrel.

Good point!

The barrels are a little on the soft side, and the pistols can suffer from heavy handed use during cocking. The heavy detent on the Model 10 I know from my own experience can cause the upward "banana barrel", but a heavy handed downward action during cocking can also bend the barrel downwards as well!

I have just had my early Diana Model 10 that had a "droop" barrel corrected as it was not possible to raise the sights high enough to hit the target at 10 metres - even after a complete rebuild with all three springs being changed and a re-seal (!), and when the rotatable barrel shroud was removed and a straight edge applied the barrel was definitely taking a nose dive.

I have a later Original Model 10 with the exact opposite problem with the more often seen upwards bent banana barrel, and this one shoots over the target at 10 meters, and is now having the barrel corrected in the opposite direction.

Both of these pistols are in pristine condition and show no outward signs of any abuse whatsoever, and both have new breach seals that show the same amount of breach seal protrusion and compression when compared with each other.

Conversely, I also have a fairly well abused ex-club early model Original Model 10 that has clearly been around the block a few times with a barrel that is as straight as a die and after a re-seal it shoots really well with plenty of sight adjustment available to cover any normally used sight picture at 10 meters.

The current generation of Giss pistol owners could be some of the most careful owners these old pistols have enjoyed as they have now become prized collectors items as well as popular classic target pistols, and if a barrel has been corrected and then given careful and respectful use there is no reason why they should ever bend again.

All three of these Model 10 pistols perform and group the best with RWS Meisterkugeln pellets - better than they do with RWS R10 pellets, and even more surprisingly it seems to make little difference if they are 4.49 or 4.50 - both work eqaully well ( but maybe not if mixed - although I have not tested this).

I originally thought it was just my own gun that had developed a touch of the "Viagra" condition. I am fettling it tomorrow with the aid of a vice, some soft vice jaws and a large tube. Mine wouldn't shoot on the card at all until I lovingly crafted (sellotaped) part of an FWB foresight element I had butchered just for the job. For some reason I am not that keen on the enclosed foresight assembly and find the gun quite unwieldy, although undoubtedly well engineered. There again, what do I know as I am a pistol novice.

Andy

Well, removed the barrel from the action and tried the tube. No effect. Decided upon a 2lb hammer and a block of wood and a couple of strikes later the barrel is as straight as a very straight thing. If you try this approach, make sure to use a couple of bits of wood or some soft vice jaws to clamp the barrel tightly before commencing the hammer violence, and obviously use a straight edge (12 steel rule) on top of breech block to check on progress. Mine must have had at least 3 mm of deflection front to back, no wonder it was shooting to the stars!
Now removed my modification to the foresight assembly as the gun is shooting where it is pointed again.
I think I might have been a bit harsh in my original assessment of this gun. Now it is straight, and I am not as frustrated, it is pleasant to shoot. Incidentally, when the action was removed from the grips, it is very apparent how well engineered the gun is. Trigger is also surprisingly good as I further reduced the sear engagement. Looking forward to setting this one up properly now at the clubs indoor 10m range.

Sorted!

I'll know what to do if my two 6m's & my 6g have either brewers droop or morning glory when they come back from service I'll be keeping one & two will be up for grabs soon Rivi & RMTC members will have 1st chance at low prices. Anyone interested see me at Rivi or pm me

[Amac]

I am presuming that Dave would straighten the barrels if required John? Anyway, the job doesn't take too long to do, and I am sure some of our members will be interested in taking one of these guns off your hands.

Andy

[zooma]

Dave will straighten a barrel if asked.

Often, when a pistol is rebuilt and returned to full power the sighting problems can become more apparent.

I asked Dave to check mine at 10 meters - not something he would normally do (or need to do) - but with Diana or Original break barrels pistols it is worth getting it checked as it could save a return journey (or two !) to get them fixed.

I think they were pretty straight tbh Andy, I'm looking forward to shooting them the 6m & 10m I shot of Bob's were very nice

My old ex-club Model 10 that really has been around the block a few times shoots superbly well, and Ray is now the proud owner of my Model 6M that you shot , so they are both in active MPL service.
