For the Scorpion 3 Pistol I see there are two SKU’s, see below. I tried comparing and can’t seem to find a difference. Looked between different model year catalogs and I only see the 91421. However on the website I only see the 91431. Any help would be appreciated, thanks.

91421 91431

Update: I reached out to my dealer and this is what he had to say. Hope this helps everyone, if this is not accurate let me know and I’ll revise.

“They changed the SKUs a few months ago on the manufacturer side, pretty typical with manufacturers. They typically change the skus for rebates or other things to track when a large batch of guns was made etc.”
