Most of the airgun reviews I posted were posted within a short interval of time, so it is interesting to look back and see how often each review has been hit, as an indication of reader interest. The following is the situation as of today, 2014/02/23, the most popular review being listed first:
Umarex Beretta 92FS (2500+) - This gun is average in terms of performance, but it is a looker and it is by far the most popular based on the number of hits - almost 1000 more than the next entry.
Beeman P17 (1500+) - Given its low price, this is not a surprise. An excellent deal if it doesn't break.
Umarex Smith and Wesson 686 (1500+) - An excellent gun with a proportional cost; its excellence still pulls it to third place.
IZH Baikal 53M (1000+) - This gun is inexpensive and has a great reputation so it is not surprising to see it at the top. I did not like my copy but it promises great performance for under $100.
Webley Alecto Ultra (1000+) - My top recommendation overall comes in fifth place. Not that surprising given that this is one of the most expensive airguns I own. It and the S&W are well worth it though.
Crosman 1377C American Classic (<1000) - This gun offers excellent accuracy for its cost, yet it falls behind the Beeman P17 and the IZH 53M - perhaps its style is not that attractive, but this is a better airgun than those.
IZH Baikal 60 (<1000) - I am surprised by the number of hits on this review. It is a great rifle, but either people are more interested in pistols than in rifles or its low power (relative to other rifles) is what keeps the interest down.
Crosman 3576W (<1000) - This is another surprise, but perhaps people that buy this gun don't bother looking for reviews and just purchase it. A solid choice.
