Even the SBE II parts that should be easy to get are almost impossible. I currently have 3 SBE II accessory parts on order from an authorized Benelli stocking dealer. They've been on order for over 2 months now. And lest you think they are weird exotic parts, they are a recoil pad, a comb insert, and a vent rib barrel. Now these are not cheap parts mind you. With a bit of discount they are $645. I prepaid them 2 months ago and the dealer can't even get a shipping date out of Benelli for any of them. As an owner of many Benellis of all descriptions (including a new one that has been "in transit" from MD for over 2 weeks now), I find this "customer support" policy inexcusable.
I get the majority of my spare Benelli parts and accessories off of gun auction sites on the net. That's really a ridiculous way to distribute parts.
These guns, parts, and accessories are far too expensive for such shoddy customer support. Benelli should hire somebody with firearms support experience and technical knowledge, who knows the typical parts and accessories that a shooter will want or need, and then bring them state side and actually STOCK them in proper numbers and on a consistant basis. Again, it's not like the profit margin isn't there to keep some commonly ordered parts on the shelves at all times.
When people ask me about Benellis I tell them they're great shooting guns, rugged guns, and tough all condition and all weather guns. But I also tell them that they're poorly supported guns.
I shoot both competitive skeet and sporting and I have given up on both Beretta (Benelli's mother company) and Perazzi (also mothered by Beretta at one point) due to this same exact policy of shoddy customer support.
