HW45 pistol.

Hello I own .22 HW45, I wondering are the barrels interchangeable ie would a .177 barrel fit?

[tinbum]

Yes, quite a simple job too

You say that but do you know you have to remove the .22 first? The .177 isn't a sliding fit.

Yes, it's a quick and easy job which takes just a few minutes. They cost about £35. Check out YouTube for a stripdown guide. If you do change it and want to sell your .22 barrel give me a shout as I'd be interested.

Ok thank you I will get a barrel but thank you for the offer.

And our very own Monsieur Tinbum has a very handy little video guide on YouTube.

The only potential problem is getting the screws out of the barrel clamp. They are easily rounded off.

Yep...agreed!

Yes, easy to round off, then very careful work with a Dremel is required to remove the screw(s) and saddle. I don't know whether it was my inattention to the exact tool fit or the original owner's. The pistol came with two Weihrauch barrels.

Weihrauch replacement saddle and screws are available.

Make sure you have an Allen key with an exact fit before you unscrew those saddle clamp screws. And don't use an Allen key made of Chinese chocolate.

Does the barrel change have any affect on the ftlbs? Specifically from .22 to .177?

Usually going .22 to .177 it will drop, but always check!

Mine was supplied in .22 but does more power in .177 mode than when in .22 mode. Bit of a surprise that. Checked with a few pellet types in both flavours. Still within limits.
