I purchased a Crosman 6100 fairly recently (built 12/86). Is this the only version of the Diana 45 with a high comb and a fairly vertical grip?

My gun shoots 675 fps with 8.4 gr JSB Exacts. Isn't this a bit slower than it should be?

What Maccari spring would work well? Can I assume that it has a leather piston seal?

Thanks for any info!

went to the "new" version somewhere around 1984 the velocity was revised upwards to 1000fps. The new models also had synthetic seals. All the 30 series guns were updated at about the same time.

My 1979 vintage RWS 45 was rated at 830 fps. In real life it does about 750 fps with an 8gr pellet.

Not sure from the pic which style yours is. If yours is the new model ; then its slow.

The pin thru the stock above the trigger tells us that this gun uses the leather seal. That is good! Yours is an interesting version of the 45 by the way. These are a great guns and respond to a tune very nicely. I just completed a tune on mine that included a Maccari spring. There is no seal update kit available from Maccari. Use the lubes that come with the spring (you have to ask for them) and you will be very happy. Note please, You need to soak the leather seal in chamber oil before reinstalling it. I suspect that yours is dry and that is why your velocity is low. Took me almost 100 shots to get the velocity back to 810fps with Hobby's after reassembly. These guns are heavy and easy to shoot very accurately.
You own a fine gun, enjoy the heck out of it.

A very nice example of this unusual gun! This gun is mechanically the same as the first model 45, however the stock is rather unique. The same stock was used on the model 35S, a late version of the model 35 barrel-cocker.

This action/stock combination was also sold in Europe with the name "RWS 45," how's that for confusing? It was of course quite different from the RWS 45 sold in the US, which had the usual ambidextrous 45 stock. I believe you are correct in saying this is the only version of this action to have a raised comb/cheekpiece type stock.

The first model 45 was made with a leather piston seal at first, but did switch to a synthetic one late in production. Being made in 1986, I would guess the gun has the latter, but there is no way to know for sure without taking it out and looking.

The speed does seem a little slow. I'm sure one of Jim's springs would work but I am not the expert in that arena.

If it turns out this gun does have a synthetic seal how about letting us know. I hate jumping around in public with a foot sticking out of my mouth. Also, My gun was manufactured 09/84. New old stock and dead nuts accurate.

Hi Jeff,
I have the RWS 45 it is exactly the same as yours except its .22 even the same year.
Now I live in the UK so I can,t have it at full power but it will do about 15 ft/lb with the right spring like a F1 Venom, it can also have a P.T.F.E washer fitted.
The 45 can be a bit fiddly to distmantle the first time, you have to maneuver the piston sleave to get the cocking slipper out so you can remove the piston.
