I have the Hammerli Forge H1 5 inch model, picked up a few weeks ago at PSA for $200 plus tax and “shipping.”. Really like it. I have a Walther PPQ22 with similar metal magazines. Both pistols feed whatever I stuff in the mags. The Hammerli even feeds my Federal Spitfire truncated cone ammo.
Someone mentioned the threaded adapter and this is a bit of a sore spot with me. The manual has no info the adapter. The wrench included with the pistol, for removing the thread protector, is so cheap it bends and spreads open, then slips off the cap.
If you make your own wrench, it is 10mm and should about 0.100” thick. The supplied wrench is about 0.075” thick.
The Walther website (the Walther site, not Hammerli) does have an info page on the adapter, when you eventually find it, but you have to read carefully. The Forge H1 uses what Walther calls the Late or long style adapter. Walther part number is 512.105 and that adapts to the US standard 1/2-28 RH thread.
Interesting: Taylor Tactical sells different thread adapters for the PPQ22 and the Forge H1. Umarex/Walther/Hammerli product support told me that most Walther (and related) 22 pistols use the same adapter, which is part number 512.105. Walther has the best price by far, $20 US, but they are out of stock.
My Forge H1 weighs 31 ounces with no mag, 34.4 ounces with a full mag. I got some cheapie walnut grips (or stocks, if you prefer) from Amazon because a black or blue metal handgun, in my opinion, needs some wood on it.
Holsters! Can’t forget that. From Amazon, I got some reproduction WWII holsters of various kinds last Christmas for my airsoft 1911. I was able to first scratch the 1911 itch with a $25 airsoft pistol but the Hammerli Forge H1 was just too irresistable! Anyway, this is supposedly a pilot or tanker chest holster. I really like this chest rig style, especially for a yard gun. It’s in front and easy to cross draw at a comfortable height, and is high so it’s not in the way when I sit down, like in the car. I‘ve got some leather ones too, and of course one of the reproduction flap holsters with ”US” on it. FYI, the canvas chest holster shown here also fits a Glock 19 size pistol, and my Heritage Single Action 22 fits also.
Ok that’s it for now. Cheers to everyone and safe shooting! Thanks to all for the helpful information you share.
