I have two of the India-made guns from Middlesex Village, a steel-barrelled blunderbuss (not the doglock, unfortunately, but alas, they were out of stock for a while), and the double-barrelled percussion howdah pistol.
I haven't had a chance to shoot the blunderbuss yet - I'm awaiting the arrival of a .311 ball mold so I can cast my own buckshot - but the lock sparks beautifully and the fit and finish, if not up to Pedersoli standards, is acceptable to me. The barrel walls seem quite thick - no tubing here, apparently.
I shot the howdah over the holidays. The right-hand lock needed some minor gunsmithing, as it had a tendency to get caught on half-cock on the way down. The tumbler had burrs and the sear nose was badly shaped, but I have the necessary skills to fix minor problems like that (took a course in gunsmithing from Penn Foster a few years ago). The nipples are oversized for #11 caps and undersized for regular musket caps (I have since been told that British musket caps tend to be a bit smaller than US musket caps), but musket caps will stay on if you pinch them and the nipples will eventually be replaced with "modern" machine-made ones. My load was 55 grains of FFg KIK powder, a pillow-ticking patch greased with "Bore Butter", and a .600 round ball. Recoil was not unpleasant, gun didn't blow up, no problems (once the lock was fixed).
So far, I'm happy with both guns.
I also have a P-1853 I bought in "as found, uncleaned condition" from IMA a couple of years ago, and which I had reworked by Todd Watts at The Blockade Runner (refinished, British marks added, etc) so I can use it as a reenactment gun. I pulled the breechplug to clean and inspect the bore (some pitting, as expected, but not to an unsafe level), and test-fired it, and it, too, is safe to shoot with live rounds. These were made under British supervision, IIRC, so I'm not really surprised.
No, I would not hesitate to buy more India-made guns from a reputable importer like Loyalist Arms or MVTCo. The Indian guns tend to come in more varieties than Italian or Japanese guns, and the real rarities (wheel-locks, English locks, and matchlocks) tend to be more affordable than the alternative - which seems to be custom guns for most of these ancient lock mechanisms (Loyalist sells a wheel-lock for about $700.00. Try to get Pedersoli to make one for that price - I dare you!).
