To tell you the truth, I'd rather have one of the newer gas piston guns than a spring piston. The gas pistons last longer and require almost zero maintenance. They also produce as high or higher velocities as spring pistons. Hatsan now offers a full line of gas-piston guns as they start to move away from spring pistons.
This is my favorite break barrel right here. It is also the least-expensive one I have. It's lightweight, indestructable, and very accurate. Just what I need for pest-control out at the pond. I've killed a lot of pesky critters with this thing. Worth every cent it cost me. I think I got mine for $99 on sale last year. I have more-powerful guns I paid more for but whenever I just go out to do some daily pest-control, this is the one I grab with a tin full of assorted pellets.
Here's from the internet....
While traditional coiled-metal springs are still produced, manufacturers are shifting heavily toward gas piston (gas ram/nitro piston) technology. Gas pistons offer smoother cocking, less vibration, and can be left cocked for extended periods without degrading, making them a popular choice for both entry-level and hunting models.
Current Market Trends
- Entry to Mid-Tier Dominance: Brands like Crosman (Benjamin) and Umarex have transitioned a massive portion of their break-barrel lines to gas piston powerplants.
- Hybrid Options: Some manufacturers now offer convertible models. For example, the Diana Model 34 EMS ships with a coiled spring but is fully engineered to accept gas pistons.
- The High-End Holdout: Premium target and field manufacturers (like Weihrauch and Air Arms) still favor coiled metal springs, as enthusiasts frequently tune and repair them for competition shooting.
