Like Wallyworld, Meijer stores in urban areas have a very small selection of common ammo. I avert my eyes when I go past their sporting goods department, I have a better selection and quantity of ammo in just one of my basement cabinets. Out in the countryside, they'll sell some common long guns, but no handguns.
Meanwhile, I put the new milled trigger guard on the CZ 453. Comparing the wood on the two, the 453 has much fancier grain in the butt area, but straighter, more sap-woody (but still impressive) walnut in the forend area. But the 455 has some crossgrain and fiddleback all the way to the muzzle.
Comparing the two, I now realize that the existing rear sight on the 455 will present me with a major problem. Unless I use ultra-high mounts, even a scope with a 33mm objective won't clear it. I can remove it, and fill in the holes with headless cap screws. Or I can try to find some kind of folding leaf sight (fat chance).
Or, I could use the official peep sight for the CA 452/453, except it seems unavailable anywhere in the western hemisphere. Or I might try a scope with no front bell, just like most of the old-time scopes. All I know is that, for now, I won't be able to do any real accuracy testing while that middle sight is just a fuzzy "V". But that cosmetic improvement to the CZ 453 just made my day.
