I’m going to look at how triggers interact with pistons in spring guns today. I thought some of the blog readers may not be aware of some of the subtleties of sears and triggers as they relate to pistons.
Two basic types of pistons
Spring pistons are latched or “caught” by their sears in 2 different ways. These 2 ways are so vastly different that they dictate what types of triggers will work with what types of pistons. Until you understand the differences, you can’t appreciate why certain triggers such as the Rekord won’t work with certain types of pistons.
A center-latched piston has a rod in its center that in some way gets latched or “caught” by the sear. When it’s latched, the sear restrains the full force of the mainspring. That can be well over 100 lbs. of force in the case of a coiled steel spring, or several hundred psi of gas pressure in the 2-piece expanding cylinder of a gas spring. The sear prevents the piston from moving until it’s released by the action of the trigger.
This topic was received well last week, so I’m doing the second list today. Several readers have reminded me of other gifts I should mention, and some of them will make today’s list. If I don’t list something you suggested, there’s a reason. These are the things I recommend without question.
Stocking stuffers/small, neat gifts
Gifts in this category don’t cost a lot but will have great meaning to airgunners. Some of them are things that shooters won’t buy for themselves.
Air Venturi Pellet Pen and Seater
Someone suggested the Air Venturi Pellet Pen and Seater, and I have to agree. This is a great gift, and it’s one that a lot of shooters won’t buy for themselves.
This is the second of my reports on the 2012 SHOT Show. There will certainly be at least one more after this, and perhaps even more, as there’s simply too much new information to pack into a single report.
The state of the airgun industry in 2012
Before I get to some specifics, I want to make a general observation. This year’s SHOT Show was different for me in a major way, because I saw for the first time that firearms shooters are beginning to understand airguns as never before. In the past, I always had to start my explanations with the cooling of the earth’s crust and then progress through the age of the dinosaurs because each firearms person I talked to thought of airguns as either toys or BB guns. This year, a lot of them were clued-in on what’s happening. They weren’t surprised by the accuracy we get, and they knew about big bores. A lot of them had some airgun experience and more than a few asked me the same kind of questions that I get from long-time readers of this blog.
This is a report I do every year to help wives and friends of airgunners with gift suggestions. There have been a lot of exciting new guns this year, and I’ll mention the ones I would pick, as well as a couple classics.
Dan Wesson revolver
One of the hottest, most desirable new guns is the Dan Wesson revolver. I’ve reported on the one that has an 8-inch barrel, but there are also revolvers with 6-inch, 4-inch and 2.5-inch barrels. These guns have the same mechanism and operate the same, but there are finish and slight design differences. Also, the shorter the barrel, the slower the velocity. They’re all priced the same, so ask your airgunner what he or she likes best and go for it. I haven’t seen a BB revolver this nice — ever! Be sure to also buy lots of CO2 cartridges and Daisy zinc-plated BBs so the fun will last. If your shooter doesn’t have a BB trap (a metal pellet trap will NOT work safely), get the Crosman 850/852 BB/pellet trap.
It’s not cheap
The price of $136 is bound to put off a lot of potential buyers, but perhaps if I tell the whole story some will look a second time. And, a second look is warranted, for this is no bargain-bin dot sight. It’s a well-engineered system, containing a dot sight with three different-colored dots, a laser and a tactical flashlight in one comprehensive package. And, speaking of the package, let’s begin there, because the box this thing comes in is enough to warm the hearts of most shooters.
