Frequently Asked Questions

What are common accuracy issues with the S&W M&P Shield 2.0 .45 ACP?

Common issues include a heavy factory trigger pull, often around 8-9 lbs, and potential rear sight drift causing shots to group low and left. These factors significantly hinder accuracy, especially at distance.

How can I improve the trigger pull on my S&W Shield 2.0 .45 ACP?

The host plans to install an Apex Duty/Carry spring kit to reduce the trigger pull weight. Aftermarket kits like Apex's are popular for improving the feel and reducing the poundage of Shield triggers.

What is the typical trigger pull weight for a S&W M&P Shield 2.0 .45 ACP?

The reviewer measured his Massachusetts-compliant model at 8 pounds 9.7 ounces. While not all models are identical, this indicates the factory trigger can be quite heavy, impacting shooter control and accuracy.

How do I fix a Shield 2.0 .45 ACP shooting low and left?

Inspect the rear sight for drift. If it's off-center (e.g., drifted left), it needs to be adjusted in the opposite direction (right) to bring the point of impact back to the center of the target.
