I don't know about Wholesale Sports and what they actually have in stock. Nothing I ever tried to order from them was in stock. P&D over in Edmonton was who I ended up getting my 453 Varmint from. They don't appear to have one in right now, but they do have 452 and 453 Americans in stock right now. That would at least let you compare triggers. Although, you would be comparing out-of-the-box triggers, which is entirely different from comparing triggers that have been adjusted. My trigger felt much different out of the box than it does now, after I adjusted it.
People are always quick to say get the 452 and the Brooks trigger kit. The problem, as I see it, with going that route is two-fold. One, there are several threads here and on rimfire central talking about how this guy has ripped them off, taken their money, and never shipped the product. He is not reliable in any sense of the word. He'll take your money, 100% guaranteed. But whether or not you'll ever see the stuff you paid for is another matter. And even if you do, who knows how long it will take. Two, you have to disassemble your trigger, probably several times, to install his kit. You may not be happy with the results of using one piece of tubing, and will have to take it all apart again, try the next tube, put it all back together again, and try again. It may not be a terribly difficult thing to do, but it is time consuming, and you're taking apart something that wasn't really meant to be taken apart after initial assembly. With the 453 trigger, you get more adjustability, and it is meant to be that way. You can turn a screw to adjust pre-travel, rather than having to take your trigger apart and try another piece of tubing and hope that one of the pieces gives you satisfactory results. With the 453, you adjust it to where you want it, and that's that. There's no luck involved, because you simply turn the screw until it is what you want. And there is no provision for over-travel at all with the 452. You're left to various hacks if you want adjustment in that department. But with the 453 it is, again, simply a matter of turning a screw until it is what you want. The only adjustment you get with a 452 is pull-weight. Not to mention you also get the added bonus of a single-set trigger. No matter how heavy you have the regular trigger set, you push it forward and instantly have another trigger that lets off at probably less than a pound. A nice little bonus.
I know it is a fair bit more for the 453. But I seriously doubt you'll be disappointed. I don't know where you are, but if you're close enough to go to Calgary to check Wholesale Sports, it might be worth your time to run out to Edmonton to P&D if Wholesale doesn't have any on hand. P&D does list both 452 and 453 Americans right now, so you could check them both out. Both triggers could be improved from what you'll see out of the box. But I think the 453's is well worth the extra dough. And, although luck of the draw with all CZs, it seems like the 453 Varmints are tending to have better wood than the 452s.
