Hard to open new Browning

Just bought a new Browning BT99 micro for my son. The gun is so stiff to open. Is there any mechanical adjustments that can be made to help make this gun easier to open and close?

Much Thanks!

Congrats on a great purchase. Brownings will give you immense pleasure and years of service if properly maintained.

Break opens are normally tight when first purchased. The best advice I can give is to open and close it while away from the range. Only a lot of use will "work it in". I'd shy away from the file as well. These guns are made pretty precise.

Many of the current-production BT-99s seem to be very tight where the forearm iron meets the receiver knuckle. Make sure to use a good quality grease in this entire area, and apply it liberally and often. If this area is dry, it can quickly gall, and make the gun very difficult to open. (Galling will leave lots of ugly marks on the metal as well).

This subject comes up every few months. If the gun opens fairly easly after you close it and open it the reason that it is "hard" to open after you shoot it is because you have to cock the mainspring and the shell ejector spring in the forearm. New O/Us are really hard to open . If it does eject the shells one solution is to remove the ejection trip rod or replace the spring in the forearm with a lighter spring. In my crossover I replaced the springs in the forearm with two 1911 springs. Now the gun just extracts the shells and does not throw them over my shoulder. If you just remove the ejector spring you my not be able to pick the shell out when it gets cold and you wear gloves. Use grease for a lube to prevent galling,that causes groves in the medal. I use white lithium grease. DO NOT USE A FILE!

Use a lighter lube. Tell your son hold the stock by the pistol grip, put the stock under his arm pit, lower his arm to hold the gun tight against his body and push his other hand to push down on the front of the gun. Tell him opening the gun will provide him some excerise to build up his forearms for greater endurance:)

With very tight tolerances, it does not take allot of lubrication. Often times just a very light grease, or heavier oil. The excess will gather in places where it eventually will start to soak into the wood. It also gains dirt, and powder residue becoming a mess. I don't think that filing for a novice is the right suggestion. Although filing the right area may be beneficial now, it will lead to a loser fit a little quicker.

Personally I think they should make a grease, with very fine abrasives to apply to these joints. This way it wears in evenly on the rounded parts, smoothing the high, or tight areas first. Of course the gun should be thoroughly cleaned after a brief break-in period.

"A couple of well placed file strokes will fix it."

Why didn't Browning think of that? They sure don't know much about making guns. They won't be in business long.
Because they're in a competitive market and it's cheaper to convince you that it's supposed to be that tight than it is to take the time to fit the forearm iron properly so they err on the tight side knowing it's easier to remove metal than it is to put it back on.
OTOH if you want to cause galling and premature wear on the hinge pin...........it's your gun?

oil not grease until it's broken in. Wipe it and reoil after every use.

Gee! John, I didn't know you worked on Browning's factory floor and know the engineering specs for each gun to be released from quality control to shipping. I love armchair know it all's they cause more warranty problems for more manufacturers than you ever can imagine, which drives the consumer prices up by the way.
