I'm curious to see how they set prices in MA.
It won't matter unless they have a special SKU for the MA only guns. If some of the guns are identical to their free state counterparts (sans mags) the pricing will be similar. Of course MA dealers will add some fluff to the top on the first few waves or so, but if the guns are identical there is nothing stopping you from going on GB/GA and buying the same gun and having it transferred in. Whether it makes economic sense to do it or not
is another story.
As far as "fix the trigger issue" goes, you're dreaming. You either have to fix it yourself or have Bruce Gray do it, and there might be a couple of other guys nationally who are capable. Otherwise nobody wants to touch an HK because of the parts situation.
At least on the guns that offer it, the LEM is the hot ticket anyways, especially if you can get the 5 pound version. This obviously isn't happening in MA, and if they offer a LEM here it will have to be gayed out to 10+ pounds, although it'll likely be easily repairable. There are basically only 2 springs that control the LEM weight.
