Whatever Garcia imported seems cloudy and erratic.
Quite so. Garcia continued the policy that Galef had used before them, putting American-sounding model names on guns that Beretta sold elsewhere under their own names, and getting Beretta to make some cosmetic changes on guns they sent to the US. Garcia's AL-1 and AL-2 are mechanically the same as Beretta's A300 and A301, although the 300 and 301 may have been available in other countries with options that blur the distinction.

Is there a reliable indicator that all Beretta 300 series shotguns have the stock shims to adjust drop? That has never been clear as some folks claim they have 303's without stock shims-- though I've never seen it.
I've heard that, too, but the people who say that are usually surprised to learn that the little plate inside the stock is actually a shim that adjusts for drop (not cast). There is no shim between the stock and the receiver until we get to the 304/390 (the 304, rare in the US, is a 390 with a 303 gas system). Every 30x gun in my collection has that drop shim, including an AL-1 and an A300. Wilson quotes the 1971 catalog (note that the A300 was introduced about 1965) as saying the A300 has the shim. I suppose some early 300's may not have had the shim, but I am not aware of any.

Is there any reliable information on what models have the carrier release on the carrier, so depressing the bolt release is not required to load the magazine, and which ones do not?
As far as I know, the 302 was the first. Parts lists do not list a carrier release plunger for earlier models. When I started shooting my AL-2, I thought I would put a later trigger group in it, but I have learned the technique now, and it really isn't hard at all. (The 302 trigger group won't work in any other model, because of the screwy magazine cutoff which also serves as the trigger group retaining pin.)

It is almost as if Beretta constantly changed configurations in the middle of the run and eventually decided to add a digit to the model later on.
I agree completely. Example - early 303's had the 302-type cutoff lever, before they went to the forearm button mid-model. I have a 303 with both types of cutoff, which makes no sense at all, unless a previous owner swapped out the barrel, forearm, and operating rod. That is possible, but I suspect Beretta just used up the parts they had on hand.
It seems odd to me that the AL-2 had a round bolt release button at first, later went to the square one, and later all models used a round one. Go figure!
The drop-in tubes are generally associated with the 302. Wilson says the earliest description of it he saw was the 1980 catalog, where it was described as the "A302 Mobilchoke". BTW, those tubes are still available from Armeria Brignoli Silvio, the factory's European parts distributor.
Randy, did you get my e-mail?
