Thanks marflow .. I’m going to get the hammer spring adjuster. eBay for $22.00. I just received a muzzle brake from Crosman, as I decided I should have ordered it in the first place. 

Crosman vs Umarex .. Crosman = 40 shots per cartridge. Umarex = 34 shots per cartridge. Both at ambient temp. The data above seems to be accurate. I may still do the spring mod, but it’s good to know the pistol at least gets the advertised shots per. Happy with the purchase. 

Thanks .. I may try the shorter spring mod. Looks to be a practical approach for sure. 

I meant 12 gram cartridges, not 80. Not sure what hole I pulled that out of !

Thanks for the reply. That looks like a viable solution, but I really don’t want to do that much modification on this new pistol. I talked to Crosman and they said heavier pellets can use more CO2. Not sure I agree with that however. Also .. it seems that Umarex cartridges may have a tad less...

I just received this pistol (see pic) it’s .177 caliber. I’m only getting about 35 usable shots from a Umarex 80g cartridge. 7 grain pellets seemed to get more than the 8.6 grain which is kinda strange. At any rate, shouldn’t I get at least 40? Also .. at 10 yards I have the Weaver rear sight...

I opted for an HW40. Just can’t escape the aura of the German craftsmanship. That said, it was a replacement for an Beeman P1 and a Weihrauch HW75. Both were returned within a two month period because of defects. So perhaps that aura has been a bit tainted recently. However .. the HW40 has...

Pyramid was very good about the return, and I appreciate the very good customer service from the tech guys and the reps. Now I have to decide what to replace it with. I’m seriously considering a Crosman 2300T. On the other hand, I can’t imagine I’d get another Weihrauch pistol with a quality...

Pyramid told me to try air tool oil on the valve stem/assembly. It did not work, unfortunately. The HW75 has a defective valve and it’s going back. Kinda wondering what happened to Weihrauch quality🤔

Here’s the schematic. Valve area circled in green. I agree with Richardo.. likely just sticking. 

I have a Weihrauch HW75 single stroke pneumatic pistol. It doesn’t consistently empty the air reservoir after firing. I noticed it when I release the retainer latch to load a new pellet, and there’s an air release/vacuum. Alternatively, every few shots, I can cock the hammer, pull the...

Yep .. agreed. I’m just saying the manual could of been worded better. If both sentences are referring to spring piston guns, then only the second sentence (never fire a spring piston gun) is necessary. Semantics I suppose :)

Jonnes .. I agree with you. See the pic highlighted text. This is from the HW75 manual, but it seems like the info has both SP and SSP models melded together. The second sentence seems redundant if the previous sentence is about spring piston guns. Confusing ... 

Hey guys .. thanks for the feedback. I understand that the HW75 can be dry fired with the methods described; but my curiosity is .. is firing it without a pellet (resistance) potentially harmful as the owners manual suggests? I can’t quite figure out why it would be. Not that I’m going to do it...

Mike .. I believe that only applies to spring piston systems. And yes, dry firing is not a good thing with them.
