HW/Weihrauch HW75 Stock options

to shoot a HW45 with a shoulder stock you needed an optional 10mm front sight riser, i wonder why you would not need one for this also
and one thing i have found is these stocks are way to short
oh they look COOL but if you are a big man good luck
so, how do i know, i got one of those that come out of Germany for my LP8, beautifully made way too short

It is an HW75, an SSP pistol, and the HW45 is a two stage springer.
 
well i know that it is not the gun that is important
the HH45 or P1 and the HW75 or P2 are the same when it comes to sights and the power that they make will not be a factor
it is a known fact that putting a shoulder stock on a HW45 changes the POI so much that the from sight had to be changed and that change was by installing a higher sight that was held in place with a grub screw or screws
it would seem that that would be the same problem that the HW75 would have with and shoulder stock
now i own these pistols

I have a shoulder Schulterstutze stock from Germany, ( currently not installed. ) it does work good with Blue ribbon model 25 Scope I have mounted. It’s easy to install there’s 2 screws to fasten it to the gun. The Stock folds also. I’m a big dude as well, & I have no issues shooting it in carbine rifle form.

Mike I respectfully disagree. Yes, the two look the same, but their different powerplants are significant.

I've owned a P1 (HW 45) and stock since the 1980's. This springer has plenty of recoil, and the "equal and opposite" reaction to the rearward-moving piston rocks the muzzle downward at the instant the pellet exits. You need the taller front sight because bolting the gun to a stock - which is anchored to your shoulder - eliminates this. (To see this effect in action: shoot the gun one-handed, at close range, with iron sights, on each power setting. It will hit HIGHER at lower power because the muzzle drops less.)

I have no experience with the P2 (HW 75), and yes, I've been wrong before! But how can a recoilless pneumatic need the taller front sight? No recoil = no movement = no change with a stock attached.

Well Mike that is something i didn't think about
but the higher sight moves your point on impact down not up if the rear sight were to stay in the original position
i was always under the impression it was how the pistol was being held
i take two fingers right hand stays the same left hand has the tall sight to bring the sight back in alinement the left hand goes down and with that the POI but hell i am just an old man i do get confused
 
It took me a long time to figure this one out, LOL.

Spring-piston recoil happens in two opposite directions of course (the reason they are so tough on scopes). The first stage is equal-and-opposite reaction to the piston's movement; the second stage, just thousandths of a second later, is a snap in the opposite direction when the piston stops.

A one-hand gun like the HW 45 - with a "backwards" piston sitting above your hand - really exaggerates the effects of recoil. The first stage pushes the piston rearward and gun forward, which rocks the muzzle downward because your hand underneath acts as a fulcrum. The second stage snaps the gun backwards. It all happens so fast you only notice the second stage - but the pellet exits during the first stage.

To put it another way...when you pull the trigger on an HW 45, you are really aiming above the target! The sight setting has to compensate for the muzzle drop. Easy to see why these guns are hard to shoot well - a consistent hold is extremely important.

Here's a lame illustration - both these pistols are sighted in for 10 meters. On the recoilless P17, the sight line is almost parallel to the bore. On the snappy backwards-sprung Tempest, not even close - if it had a stock restraining recoil movement, it too would need a taller front sight.

Yes the recoil affects the POI so much that I couldn't use the 1/2 power setting with full powers zero. Mounting a stock will of course change the POI as well.

The HW75 is recoiless.
It uses a different grip configuration than the 45. The pistol grip frame is cut short and the stock fits around it. The HW45 takes 1911 grips.
See the photo to see where the frame stops.

I think fitting a HW45 shoulder stock to a 75 would take some engineering. 👍

Excellent example!
I had a Tempest once. It was my first pistol. I bought a Bianchi Holster fot it. It was my first dealing with Robert Beemans wonderful era. 👍

I learned the POI lesson many moons ago, when my P1 was new. I was shooting at a pellet trap in my garage on the high power setting and got it dialed in pretty well. I tried some shots at low power...but mysteriously no new holes appeared in the target...because they had passed over the top of the trap and were buried in the wall beyond! :oops:

The HW 75 was originally released as the "Beeman P2" in the US. Early ones had the full grip frame so would work fine with the Beeman P1 stock. And there are various newer stock designs out there which are designed for the cut-down frame now used on the 45 and 75.

A note on the original P1 stock - Beeman recommended attaching it with the gun's grip screws, but those are too short for a secure hold in the soft alloy frame. I highly recommend finding some longer screws.

The P1 POI issue was early for me as well.
My P1 was ordered on a debut introductory sale, from a flyer that Beeman put out introducing the gun. There were no pics at the time only drawings. I believe that sale funded the first shipment over.
